Mobile Sink Based Improved Energy Efficient Routing Algorithm Using Cluster Coordinator Node in Wireless Sensor Network

Abstract

It is imperative to perform energy-effective data transmission over a Wireless Sensor Network (WSN) to maintain the efficacy of the network; the sensor nodes in the network are responsible for relaying the data from the source to the destination node. To this end, a Mobile sink is introduced by the researchers to enhance the transmission ability. Though it is proved to be efficacious still energy consumption of the nodes is higher that in turn affects the reliability of the network. Researchers have developed various methods in which they have used the mobile sink that work in a static method. Thus, a novel approach is designed in which the network is evenly divided into five sections in which sensor nodes are equally distributed. The data transmission occurred through the Cluster Coordinator node (CCO) as they are rechargeable and assist in passing data to the mobile sink in each cluster with high efficacy. The simulation of the model is performed in MATLAB software for different network areas and different radius of sink mobility to evaluate the efficacy of the network in energy consumptions. The comparison with the traditional method demonstrated that incorporation of the CCO enabled the network to consume less energy and increase the network life span of the WSN area for data communication.
