Lifetime Enhancement of Wireless Sensor Networks Using Energy Centric Clustering Algorithm

The major issue in Wireless Sensor Networks (WSN) is energy consumption. Over the past years, various protocols have been proposed to prolong the lifetime and minimize the energy consumption of the sensor node. The main limitations in WSN are limited battery capacity, communication range and storage capacity. A suitable routing protocol is required to improve the network lifetime and minimize energy consumption. In this paper, we propose an Energy Centric Clustering Routing Protocol for WSNs (EC2RP). In EC2RP, node residual energy and distance parameters are considered. Further, the data aggregation rate is proposed which allows the cluster heads (CH) nodes to aggregate the data before it sending to the next CH node or base station node. The simulation results show that EC2RP reduces energy consumption and extends the network lifetime.
