Leach based routing protocol in wireless sensor networks

2014

Due to the wide range of applications the use of wireless sensor networks (WSNs) in past few years have increased a lot and it has become a hot research area now a days. One of the important issues in wireless sensor network is the inherent limited battery power in network sensor nodes. Since most of the energy is consumed by the radio transmission and reception, energy efficient routing protocol is required to enhance the lifetime of WSN. Based on the network structure, there are two broad categories of routing protocols in WSNs: flat routing and hierarchical routing. Many researchers are working on these different routing protocols of wireless sensor networks. In this paper the focus is mainly on the survey of the energy-efficient hierarchical cluster-based routing protocols based on Low-Energy Adaptive Clustering Hierarchy (LEACH) which is the first and most popular energy-efficient hierarchical clustering algorithm for WSNs. In this paper we have outlined the advantages of clustering for WSNs, and systematically analyze different LEACH based WSN clustering routing protocols.

A Wireless sensor network (WSN) has been extensively used in a specified area for monitoring environment conditions such as temperature, air pressure, light, humidity, motion or vibration and can communicate with each other using a wireless radio device. Normally, sensor nodes in wireless sensor networks (WSNs) have resource constraints like limited energy, low storage capacity and weak computing ability. Therefore the life time of the Wireless sensor network (WSNs) highly depends on the energy consumption of sensors. This surveying paper highlight the energy-efficient hierarchical cluster based routing protocols based on Low-Energy Adaptive Clustering Hierarchy (LEACH), which is considered as the most popular routing protocol for WSNs, that use cluster based routing in order to minimize the energy consumption. In this paper there is a complete study of different LEACH based WSN clustering routing protocols.

A new two layer hierarchical routing protocol called Cluster Based Hierarchical Routing Protocol (CBHRP) is proposed in this paper. It is an extension of LEACH routing protocol. We introduce cluster head-set idea for cluster-based routing where several clusters are formed with the deployed sensors to collect information from target field. On rotation basis, a head-set member receives data from the neighbor nodes and transmits the aggregated results to the distance base station. This protocol reduces energy consumption quite significantly and prolongs the life time of sensor network. It is found that CBHRP performs better than other well accepted hierarchical routing protocols like LEACH in term of energy consumption and time requirement.

This paper propose a new low power consumption routing protocol for wireless sensor networks based on clustering approach. The suggest protocol is to use energy more evenly selected node cluster-heads, and save the energy dissipated when routing captured data to the base station. Simulation results have shown that suggest protocol allows a reduction in energy dissipation and a life of greater network. Various hierarchical routing solutions practice clustering techniques, to reduce energy consumption and enable scaling; The KOCA (K-hop Overlapping Clustering Algorithm) forms overlapped K-Clusters (cluster with K-hop) to enable inter-cluster multi-hop routing; and the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol, whichever arrange the sensors nodes as a layered clustering construction to decrease data delivery time. In order to illustrate the substantial assets of KOCA, the simulations show the impact of mobility on the performance of sensors LEACH and M-LEACH (Multi-hop Low Energy Adaptive Clustering Hierarchy) in WSNs (Wireless sensor networks) environments. Therefore, the results obtained have shown that the mobility has a significant impact on the performance of these two protocols in terms of lifetime of the network and the number of data sent to the base station packets. The KOCA provided better performance than these two protocols. The simulations applying the NS2 simulator present the protocol perform good presentation in both delivering data and energy conservation. It create a small number of clusters, and distributes energy consumption equally on the network.

In Wireless sensor networks, several routing protocols have been developed to improve the various parameters such as stability period, throughput etc .After a homogenous protocol leach, many heterogeneous protocol were developed which successfully improved the routing in WSNs .In this Paper we studied one of the heterogeneous protocol DEEC and its improved version EDEEC and we tried to work on two parameters i.e. Stability period and throughput of the network to improve these further .In this Paper we introduced a new node i.e. super advanced node with the existing heterogeneous nodes in the EDEEC which successfully improved its stability period and we also incorporated a reactive protocol i.e. TEEN in our paper to make our network communication more efficient .Thus we used the best of EDEEC and TEEN and made TADEEC protocol. This has been simulated in Matlab and results have outperformed the LEACH, DEEC, EDEEC etc.

From hierarchical routing protocols, Low-Energy Adaptive Clustering Hierarchy (LEACH) has been considered as one of the effective algorithms that optimize energy and prolong the lifetime of network. In this paper, we propose a new approach of electing Cluster Head (CH) based on LEACH protocol. The selection of Cluster Head (CH) in LEACH is carried out randomly. In our proposed approach, we consider three fundamental criteria: the remaining energy, the number of neighbours within cluster range and the distance between node and CH. In fact, in our algorithm, we include these factors in calculation of threshold. Simulation results shows that our proposed approach beats LEACH protocol in regards of prolonging the lifetime of network and saving residual energy.

Wireless sensor network are sophisticated systems that are used to collect data from an inaccessible environment. They consist of base station and hundred to thousand of tiny nodes called sensor nodes. Nodes in the sensor network are constrained by energy. The sensor networks where base station is very distant from the sensor field, the energy efficiency in the working of sensor networks plays an important role in the lifetime of the sensor networks. To prolong the life of the sensor network energy efficient techniques for routing is an important issue. In this paper we proposed a new algorithm for cluster head selection in each cluster for each round of communication. The clusters are fixed through out the network life time. Our proposed work is based on LEACH and LEACH-C. The protocol works efficiently to increase the overall network lifetime and outperforms LEACH in terms of minimizing the overall energy consumption.

Wireless Sensor Network (WSN) is infrastructure less. Sensors usually rely on their battery for power, which cannot be recharge or replaced.
