ROUTING PROTOCOL FOR IoV-FOG NETWORK SUPPORTED BY SDN

Telecommunications and Radio Engineering, 2020

Internet of Vehicles (IoV) includes communications of various types of sensors which are put in the cars. The fog devices transmit the answers to the sensors after executing the launched jobs from these sensors quickly. Due to the movement, the source vehicle of some job may be going out from a coverage region for a fog device during an execution period. Accordingly, a response doesn't deliver to the source vehicle, and as a result, the deadline for most tasks will be passed, and the throughput will be reduced. This paper introduces a new environment for IoV-Fog network by exploiting hierarchical Software Defined Network (SDN). In addition, a routing protocol named Delay-Efficient Routing approach for IoV depending on Fog and SDN (DRIFS) is suggested. DRIFS is applied in the SDN orchestrators to build efficient paths. Also taken into consideration, the speed and location of the cars, as well as the remaining bandwidth. The simulation results illustrate the suggested method is powerful compared with the IoV-Fog system and IoV-Fog-central SDN environments according to average delay and successfully transmission ratio.

Proactive load balancing mechanism for fog computing supported by parked vehicles in IoV-SDN

These sensors generate different tasks that should be analyzed and processed in some given period of time. They send the tasks to the cloud servers but these sending operations increase bandwidth consumption and latency. Fog computing is a simple cloud at the network edge that is used to process the jobs in a short period of time instead of sending them to cloud computing facilities. In some situations, fog computing cannot execute some tasks due to lack of resources. Thus, in these situations it transfers them to cloud computing that leads to an increase in latency and bandwidth occupation again. Moreover, several fog servers may be fuelled while other servers are empty. This implies an unfair distribution of jobs. In this research study, we shall merge the software defined network (SDN) with IoV and fog computing and use the parked vehicle as assistant fog computing node. This can improve the capabilities of the fog computing layer and help in decreasing the number of migrated tasks to the cloud servers. This increases the ratio of time sensitive tasks that meet the deadline. In addition, a new load balancing strategy is proposed. It works proactively to balance the load locally and globally by the local fog managers and SDN controller, respectively. The simulation experiments show that the proposed system is more efficient than VANET-Fog-Cloud and IoV-Fog-Cloud frameworks in terms of average response time and percentage of bandwidth consumption, meeting the deadline, and resource utilization.

At the recent years, there is large evolution in the industry of electric vehicles and in the near future, the normal vehicles may be replaced with electric vehicles. The energy consumption of these vehicles depends on the vehicle body size and weight, passengers' weight, mobility speed, and vehicle communications. In this paper, we focus only on vehicle communications and propose a new concept called Electrical Vehicular Ad Hoc Network (E-VANET). E-VANET is a new trend of vehicular ad hoc networks (VANET) which composes of connecting a group of electric vehicles with each other and with the infrastructure to exchange information. In addition to the challenges of VANET such as mobility, routing, location awareness, etc., the main challenge in E-VANET is energy consumption that needs a great research effort to be reduced. Therefore, it is necessary to highlight E-VANET and new concepts, standards, and technologies that can be used to enhance its performance and reduce energy consumption. The main goal of this paper is to explain the concept of this new network type, its architectures, applications, and challenges as well as the technologies that can be merged with it to increase the network lifetime like software-defined network, fog computing, internet of vehicles (IoV) and cloud computing. This paper can open the door in front of the researchers to contribute in enhancing the work of E-VANET.

The present paper provides a hybrid method for IT software risks identification. Software projects possess different features which increase the project failure possibilities. Therefore, the present work integrate the Artificial Neural network with the Analytic Hierarchy Process (AHP-ANN) in order to solve the problem of software project estimation in early stage. The questionnaire developed to find out the risk functional model and provide the proposed method with proper data. The results observe a major common risk in software projects is the insufficient knowledge based on different software project life cycle stages. Also, there are some other important factors in software projects such as lack of good estimation in project scheduling, poor definition of project requirements which cause human errors.

Performance Comparison of Transmission Control Protocol and User Datagram Protocol Over Wireless Networks

This study measures the performance of Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) over WiFi. Various network-related issues such as packet loss, error control, and reliability are measured. From the NS2 results, UDP provides better results for real-time data in WiFi networks than TCP. Loss of packets or data occurs when UDP is used. However, the throughput of UDP is higher than that of TCP because during a handover, the TCP window size is reset, thus decreasing the throughput. Further, the handover latencies for TCP are higher than those for UDP.

Multicast routing strategy for SDN-cluster based MANET

The multicast routing problem is one of the NP-complete problems. Therefore, the need for a new power-aware approach to select an optimum multicast path with minimum power consumption that can enhance the performance and increase the lifetime of MANET has become urgent. Software defined network (SDN) is a new technique that can solve many problems of the traditional networks by dividing the architecture into data part and control part. This paper presents three power-aware multicast routing strategies for MANET. First one called a Reactive Multicast routing strategy for cluster based MANET by using SDN (RMCMS), second one called proactive multicast routing strategy for cluster based MANET by using SDN (PMCMS) and third one represents modification of PMCMS called M-PMCMS. Moreover, it produces a new mathematical model to build a multicast tre...
