Wireless Sensor and Mobile Adhoc Networks

In order to maximize the network's lifetime and ensure the connectivity among the nodes, most topology management practices use a subgroup of nodes for routing. This paper provides an in-depth look at existing topology management control algorithms in Multi-state structure. We suggest a new algorithm based on Geographical Adaptive Fidelity (GAF) and Adaptive Self-Configuring Sensor Networks Topology (ASCENT). The new proposed algorithm outperforms both GAF and ASCENT algorithms.

Divergent modulation schemes have been proposed for the Internet of Things (IoT). Low Power Wide Area Networks (LPWAN) technologies are gaining unprecedented acceptance in IoT application of sensor networks. Chirp Spread Spectrum (CSS) is a prominent modulation technique proposed for LPWAN. Chirps can traverse long distance and are resilient to noise and Doppler effects. Noise resilience along with transmission range and low power requirement makes CSS a preferred modulation scheme for sensor networks. LoRaWAN TM , with its physical (PHY) layer using CSS, has emerged as the widely accepted LPWAN solution. By using CSS modulation with orthogonal spreading factors (SF), LoRa offers wide coverage to LPWAN applications while supporting a high volume of devices. However, scalability performance of CSS has not been inadequately modeled. As with the suitability of the modulation scheme, there are concerns on how chirps interact with the surrounding as the number of deployments bursts out into higher volumes. We evaluate CSS at ISM band 868 MHz for spreading factor 7 to 12 at bandwidth 125 kHz for performance and scalability. Simultaneous transmissions were simulated with repeated iterations and conclusions are arrived on collisions rate, packet error rate, and bit error. Suitability of using CSS for sensor networks for future deployments is commended.

The use of the Internet is growing in this day and age, so another area has developed to use the Internet, called Internet of Things (IoT). It facilitates the machines and objects to communicate, compute and coordinate with each other. It is an enabler for the intelligence affixed to several essential features of the modern world, such as homes, hospitals, buildings, transports and cities. The security and privacy are some of the critical issues related to the wide application of IoT. Therefore, these issues prevent the wide adoption of the IoT. In this paper, we are presenting an overview about different layered architectures of IoT and attacks regarding security from the perspective of layers. In addition, a review of mechanisms that provide solutions to these issues is presented with their limitations. Furthermore, we have suggested a new secure layered architecture of IoT to overcome these issues.

Extensive studies have been carried out for reducing the handover time of wireless mobile network at medium access control (MAC) layer. However, none of them show the impact of reduced handover time on the overall performance of wireless mobile networks. This paper presents a quantitative analysis to show the impact of reduced handover time on the performance of wireless mobile networks. The proposed quantitative model incorporates many critical performance parameters involve in reducing the handover time for wireless mobile networks. In addition, we analyze the use of active scanning technique with comparatively shorter beacon interval time in a handoff process. Our experiments verify that the active scanning can reduce the overall handover time at MAC layer if comparatively shorter beacon intervals are utilized for packet transmission. The performance measures adopted in this paper for experimental verifications are network throughput under different network loads.

The hierarchical routing algorithm is categorized as a kind of routing method using node clustering to create a hierarchical structure in large‐scale mobile ad hoc network (LMANET). In this paper, we proposed a new hierarchical clustering algorithm (HCAL) and a corresponded protocol for hierarchical routing in LMANET. The HCAL is designed based on a cost metric in the form of the link expiration time and node's relative degree. Correspondingly, the routing protocol for HCAL adopts a reactive protocol to control the existing cluster head (CH) nodes and handle proactive nodes to be considered as a cluster in LMANET. Hierarchical clustering algorithm jointly utilizes table‐driven and on‐demand routing by using a combined weight metric to search dominant set of nodes. This set is composed by link expiration time and node's relative degree to establish the intra/intercommunication paths in LMANET. The performance of the proposed algorithm and protocol is numerically evaluated in average end‐ to‐end delay, number of CH per round, iteration count between the CHs, average CH keeping time, normalized routing overhead, and packet delivery ratio over a number of randomly generated benchmark scenarios. Furthermore, to corroborate the actual effectiveness of the HCAL algorithm, extensive performance comparisons are carried out with some state‐of‐the‐art routing algorithms, namely, Dynamic Doppler Velocity Clustering, Signal Characteristic‐Based Clustering, Dynamic Link Duration Clustering, and mobility‐based clustering algorithms. KEYWORDS cluster head (CH), clustering, cost metrics, hierarchical routing algorithm, mobile ad hoc networks (MANET)

A VLAN is a logical connection that allows hosts to be grouped together in the same broadcast domain, so that packets are delivered only to ports that are combined to the same VLAN. We can improve wireless network performance and save bandwidth through the characteristic VLAN network. In addition, the implementation of VLAN greatly improves wireless network security by reducing the number of hosts receiving copies of frames broadcast by switches, thus keeping hosts holding critical data on a separate VLAN. In this paper we compare wireless network with VLAN via wireless network. The proposed network is evaluated within terms of delay and average throughput using web browsing applications and file transfer in heavy traffic. The simulation was carried out using OPNET 14.5 modeler and the results show that the use of VLAN via wireless network improved performance by reducing traffic resulting in a minimized delay time. Furthermore, VLAN implementation reduces network throughput because...

A VLAN is a logical rather than physical connection that allows grouping hosts together in the same broadcast domain, so that packets are only delivered to ports that are combined to the same VLAN. By characteristic VLAN network, we can improve efficiency of wireless network and save bandwidth. Furthermore, implementing VLAN greatly improves wireless network security by decreasing the number of hosts that receive copies of frames broadcasted by switches, so hosts holding critical data are kept on a separate VLAN. This paper compares wireless network with wireless network having VLAN deployment. The proposed Network is evaluated in terms of average throughput and delay using file transfer in heavy traffic and web browsing applications. The simulation was carried out by employing OPNET 14.5 modeler simulation and the results show that the use of VLAN via wireless network had improved the performance by decreasing the traffic resulting in minimizing delay time. In addition, implementing VLAN reduces the network throughput because the traffic that is received and forwarded has a positive relationship with throughput. Furthermore, we investigated to improve the throughput in a wireless VLAN network by using adhoc routing protocols. Evaluation, comparison of broad adhoc routing protocols like AODV, DSR, OLSR, TORA and GPR are conducted in order to show the effect of the proposed VLAN on the performance results, like throughput and delay.

The advancement of wireless sensor networks yields a variety of wireless sensor network for wildlife tracking. One typical application for wireless sensor networks is in animal tracking and monitoring in wildlife environments. A significant number of studies have been done in tracking animals with sensor networks. However from the recent literature it is observed that there is no much study has been done on an intelligent real time sensor network that is capable to alerting the rangers an incidence of animal poaching before it happened. In this paper an intelligent wireless sensor system for tracking and monitoring rhinos and elephants is proposed.

Mobile wireless sensor networks (MWSNs) have emerged and shifted the focus from the typical static wireless sensor networks to networks with mobile sensor nodes that are capable to sense the various types of events. Also, they can change their position frequently in a specific sensing area. The applications of the MWSNs can be widely divided into time-driven, event-driven, on-demand and tracking based applications. Mobile sensor node architecture, residual energy utilization, mobility, topology, scalability, localiza-tion, data collection routing, Quality of Service (QoS), etc., are the key factors to design an energy efficient MWSNs for some specific purpose. This chapter deals with an overview of the MWSNs and a few significant phenomena to design an energy efficient MWSNs to the large-scale environment.

Internet of Things (IoT) has emerged as a global network, which intelligently connects different devices or systems which are having self-configuring capabilities. The key idea is to bind or to connect miscellaneous devices or objects via wireless or wired connections along with unique addressing system and make omnipresent environment where an individual can communicate at any time with digital and physical word. It has conspicuous vulnerabilities because of increasing number of omnipresent devices. That is why for conveying data at application layer, resource constrained machines are supposed to exploit Constrained Application Protocol (CoAP) which was standardized by Internet Engineering Task Force (IETF). CoAP has previously accepted as the paradigm protocol for IoT systems. But, privacy of CoAP is yet an open Challenge. As it influences an individual's daily life it is indispensable to allow security services like authentication, confidentiality, authorization etc. This survey presents an overview of CoAP as well as current situation of security and privacy in Internet of Things that is required to be solved and discuss the further work.

VANET is a subset of MANET in which communication among the vehicles may be done using vehicle-to-vehicle or roadside infrastructure. But there may be chances of attacks in VANET due to mobility of nodes and random change in topology. One of the prominent attack is Sybil attack in which attacker creates multiple false identities to disturb the functionality of VANET. In literature many solution have been proposed for detection and protection of vehicles from Sybil attack. In the current work, authors have proposed a Sybil node detection technique based on timestamp mechanism. In this work timestamp is a unique certificate provided by RSU to all vehicles on the road in VANET. In the proposed work for node discovery and data transmission, we used Ad-hoc On Demand Distance Vector (AODV) Routing protocol and timestamp as a hash function of public key and for detection of the Sybil node implemented through NS2 simulator.

Wireless Sensor Networks (WSNs) are playing remarkable contribution in real time decision making by actuating the surroundings of environment. As a consequence, the contemporary agriculture is now using WSNs technology for better crop production, such as irrigation scheduling based on moisture level data sensed by the sensors. Since WSNs are deployed in constraints environment, the life time of sensors is very crucial for normal operation of the networks. In this regard routing protocol is a prime factor for the prolonged life time of sensors. This research focuses the performances analysis of some clustering based routing protocols to select the best routing protocol. Four algorithms are considered which are Low Energy Adaptive Clustering Hierarchy (LEACH), Threshold Sensitive Energy Efficient sensor Network (TEEN), Stable Election Protocol (SEP) and Energy Aware Multi Hop Multi Path (EAMMH).The simulation is carried out in Matlab framework by using the mathematical models of those...

Modbus is the de facto standard communication protocol for the industrial world. It was initially designed to be used in serial communications (Modbus RTU/ASCII). However, not long ago, it was adapted to TCP due to the increasing popularity of the TCP/IP stack. Since it was originally designed for controlled serial lines, Modbus does not have any security features. In this paper, we wrote several benchmarks to evaluate the performance of networking devices that run Modbus TCP. Parameters reported by our benchmarks include: (1) response time for Modbus requests, (2) maximum number of requests successfully handled by Modbus devices in a specific amount of time, and (3) monitoring of Modbus devices when suffering a Distributed Denial of Service attack. Due to the growing adoption of IoT technologies, we also selected two widely known and inexpensive development boards (ESP8266 and Raspberry Pi 3 B+/OpenPLC) to realize a performance evaluation of Modbus TCP.

Using Wireless sensor Networks (WSNs) in health care system has yielded an amazing effort in recent years. However, in most of those researches, tasks like detector processing, health state choices creating and emergency messages causing are completed by a foreign server. Transmission and handing with an oversized scale of knowledge from body sensors consume plenty of communication resource, bring a burden to the remote server and delay the choice time and notification time. During this paper, we tend to gift a paradigm of a sensible entranceway that we've enforced. This entranceway is associate degree interconnection and services management platform particularly for WSN health care systems reception setting. By building a bridge between a WSN and public communication networks, associate degreed being compatible with an aboard knowledge call system and a lightweight info, our sensible entranceway system is enabled to form patients' health state choices in low-power and affordable embedded system and find quicker time interval o the emergencies. We've conjointly designed the communication protocols between WSN, entranceway and remote servers. To boot LAN, Wi-Fi and GSM/GPRS communication module are integrated into the sensible entranceway so as to report and send word info to care-givers.

Limited energy resources and sensor nodes’ adaptability with the surrounding environment play a significant role in the sustainable Wireless Sensor Networks. This paper proposes a novel, dynamic, selforganizing opportunistic clustering using Hesitant Fuzzy Linguistic Term Analysis- based Multi-Criteria Decision Modeling methodology in order to overcome the CH decision-making problems and network lifetime bottlenecks. The asynchronous sleep/awake cycle strategy could be exploited to make an opportunistic connection between sensor nodes using opportunistic connection random graph. Every node in the network observe the node gain degree, energy welfare, relative thermal entropy, link connectivity, expected optimal hop, link quality factor etc. to form the criteria for Hesitant Fuzzy Linguistic Term Set. It makes the node to evaluate its current state and make the decision about the required action (‘CH’, ‘CM’ or ‘relay’). Our proposed scheme leads to an improvement in network lifetime, packet delivery ratio and overall energy consumption against existing benchmarks.

Media is everywhere and we live immerse “in” it (Deuze, 2012). Interface design is working on diluting boundaries between human and machines (HCI), incorporating the devices in our daily life by ful lling our motivations and, at the same time, generating interactions to arise them.
Wonder, love, hate, desire, joy, and sadness; the six primary passions of the soul described by Descartes (1649) are increasingly incorporated in the mobile interface design and construction of messages, altering the way our brain, and speci cally our memory, deals with general content and personal data.
It has already been proven the connection between emotions and health, being our brain the technology that links both (MIT). Also it has been recently demonstrated the relation between memories and place – process of episodic memory formation - (Meyer, 2014). Then, we have wearable technologies and media life, o ering constant motivations to our desires and feelings. Therefore, as much as they could ful ll them, we would incorporate them too in our routine. Thus, emotion and motivation seem to be key elements and technologies should work as our brain to stablish the proper connection between users and interfaces.

MANET environment was represented by a combination of node position, mobility speed, node type, and number of nodes. In this paper, a novel system for MANET environment evaluation is proposed by involving fuzzy multi-criteria decision maker (FMCDM) to reflect the importance of the MANET environment on the overall protocols performance. The proposed system combined with another system that previously suggested for MANET protocol evaluation. the outputs of these systems are merged to produce one single crisp value in interval [0 1]. Then, a case study for an office is implemented using OPNET 14.5 simulator to test the proposed system. results proved that MANET environment could be used to enhance the QoS of the protocol. in another world, factors along with inherent characteristics of Ad-hoc networks may result in unpredictable variations in the overall network performance.

Wireless Sensor Network (WSN) is commonly used to collect information from a remote area and one of the most important challenges associated with WSN is to monitor all targets in a given area while maximizing network lifetime. In wireless communication, energy consumption is proportional to the breadth of sensing range and path loss exponent. Hence, the energy consumption of communication can be minimized by varying the sensing range and decreasing the number of messages being sent. Sensing energy can be optimized by reducing the repeated coverage target. In this paper, an Adaptive Sensor Sensing Range (ASSR) technique is proposed to maximize the WSN Lifetime. This work considers a sensor network with an adaptive sensing range that are randomly deployed in the monitoring area. The sensor is adaptive in nature and can be modified in order to save power while achieving maximum time of monitoring to increase the lifetime of WSN network. The objective of ASSR is to find the best sensing range for each sensor to cover all targets in the network, which yields maximize the time of monitoring of all targets and eliminating double sensing for the same target. Experiments were conducted using an NS3 simulator to verify our proposed technique. Results show that ASSR is capable to improve the network lifetime by 20% as compared to other recent techniques in the case of a small network while achieving an 8% improvement for the case of a large networks.

Recently, sensor networks have been used in a wide range of applications, and interest in sensor node performance has increased. A sensor network is composed of tiny nodes with limited resources. The sensor network communicates between nodes in a configured network through self-organization. An energyefficient security protocol with a hierarchy structure with various advantages has been proposed to prolong the network lifetime of sensor networks. But due to structural problems in traditional protocols, nodes located upstream tend to consume relatively high energy compared to other nodes. A network protocol should be considered to provide minimal security and efficient allocation of energy consumption by nodes to increase the network lifetime. In this paper, we introduce a solution to solve the bottleneck problem through an efficient message route selection method. The proposed method selects an efficient messaging path using GA and fuzzy logic composed of multiple rules. Message route selection plays an important role in controlling the load balancing of nodes. A principal benefit of the proposed scheme is the potential portability of the clustering-based protocol. In addition, the proposed method is updated to find the optimal path through the genetic algorithm to respond to various environments. We demonstrated the effectiveness of the proposed method through an experiment in which the proposed method is applied to a probabilistic voting-based filtering scheme that is one of the cluster-based security schemes.

This paper simulates and investigates the performance of four widely-used channel estimation techniques for MIMO-OFDM wireless communication systems; namely, super imposed pilot (SIP), comb-type, space-time block coding (STBC), and space-frequency block coding (SFBC) techniques. The performance is evaluated through a number of MATLab simulations, where the bit-error rate (BER) and the mean square error (MSE) are estimated and compared for different levels of signal-to-noise ratio (SNR). The simulation results demonstrate that the comb-type channel estimation and the SIP techniques overwhelmed the performance of the STFC and STBC techniques in terms of both bit-error rate (BER) and mean square error (MSE).

The paper presents a Riverbed simulator implementation with both routing and medium access control (MAC) protocols for mobile ad-hoc network wireless networks with multi-beam smart antennas (MBSAs). As one of the latest promising antenna techniques, MBSAs can achieve concurrent transmissions / receptions in multiple directions/beams. Thus it can significantly improve the network throughput. However, so far there is still no accurate network simulator that can measure the MBSA-based routing/MAC protocol performance. In this paper, we describe the simulation models with the implementation of MBSA antenna model in physical layer, MAC layer, and routing layer protocols, all in Riverbed Modeler. We will compare two routing scenarios, i.e., multi-hop diamond routing scenario and multi-path pipe routing. We will analyze the network performance for those two scenarios and illustrate the advantages of using MBSAs in wireless networks.
