Energy Consumption Rate based Stable Election Protocol (ECRSEP) for WSNs

Abstract

In recent few years Wireless Sensor Networks (WSNs) have seen an increased interest in various applications like border field security, disaster management and medical applications. So large number of sensor nodes are deployed for such applications, which can work autonomously. Due to small power batteries in WSNs, efficient utilization of battery power is an important factor. Clustering is an efficient technique to extend life time of sensor networks by reducing the energy consumption. In this paper, we propose a new protocol; Energy Consumption Rate based Stable Election Protocol (ECRSEP). Our CH selection scheme is based on the weighted election probabilities of each node according to the Energy Consumption Rate (ECR) of each node. We compare results of our proposed protocol with Low Energy Adaptive Clustering Hierarchy (LEACH), Distributed Energy Efficient Clustering (DEEC), Stable Election Protocol (SEP), and Enhanced SEP(ESEP). Our simulation results show that our proposed protocol, ECRSEP outperforms all these protocols in terms of network stability and network lifetime.

A Review on Energy Efficient Clustering Protocol of Heterogeneous Wireless Sensor Network

“…Some of the time other parameter is also added with energy required for current round by the selected CH [16,21,22,41].…”

“…3) Throughput of the network: Number of messages transacted over the network towards base station per cluster cycle or cluster round is termed as throughput [1,11,13,17,18,[21][22][23][24]26,27,29,[30][31][32][33][34][35]37,41,42,45,[46][47][48]57,58,61,64].…”

Effectiveness of Power Harvesting in Hierarchical Routing Protocols in Wireless Sensor Networks

“…The design challenges in sensor networks involve the following main aspects [22][23][24][25][26] There are two types of network clustering schemes. Firstly, clustering algorithms applied on homogeneous networks, where all nodes have same initial energy like Low Energy Adaptive Clustering Hierarchy (LEACH) [27][28][29][30] used the probabilistic method to elect the CH and the probability of choosing the cluster head decides after how many rounds a node can be again cluster head. Secondly, clustering algorithms applied on heterogeneous networks, where a few sensor nodes have high initial energy from others like stable election protocol (SEP) [5].…”

“…Various enhanced versions of SEP routing protocols were proposed like ESEP [28], ZSEP [31] etc. ESEP used three heterogeneity levels using the normal, intermediate and advanced nodes where increasing initial energies respectively.…”
