An Enhanced Energy-Aware Dynamic Routing Protocol for Wireless Sensor Networks

Abstract

Wireless sensor network (WSN) becomes a challenging platform where the nodes are used to sense and monitor the target region, and then send the data to the base station (BS) through multihop routing. Because of restricted abilities, the nodes are started to face energy issues and difficult routing process which results in the failure of data transmission and incurs high delay. This paper presents an enhanced energy aware dynamic routing (EEADR) protocol for WSN for load balancing over a larger group of active nodes. The presented EEADR protocol intends to select the gateway node for load balancing over a large set of active nodes thus enhances the network lifetime. The EEADR protocol elects the proper location of the CHs closer to the energy centroid position and for gateway node selection to communicate the data towards the BS via multi-hop transmission. It helps to improve the coverage of CH and reduces the transmission power of CH. In order to investigate the proficient performance of the presented EEADR protocol, a set of simulations were performed and the results are examined under distinct aspects. The obtained experimental results pointed out the betterment of the EEADR technique over the other compared methods.
