Energy Efficient Routing Protocol Using Next Cluster Head Selection Process In Two-Level Hierarchy For Wireless Sensor Network

Abstract

Wireless Sensor Network (WSN) has played a vital role in monitoring fire alarms, smoke, and security in smart buildings and shopping malls, as well as monitoring the environment and thread security. In this paper, the proposed Energy Efficient Next Cluster Head Based Two-Level Hierarchy Routing Protocol (EE-CHRP) separates the network into two tiers. Using the maximum Residual Energy(RE) of the Sensor Node (SN), shortest Base Station (BS) distance and maximum neighbour nodes as network parameters, the Next Cluster Head (NCH) is selected during the section of Cluster Heads (CH) hence the repeatedly CH selection process is reduced to improve the network's efficiency. The communication between cluster heads is conducted within the network. One of the cluster nodes functions as a Cluster Head (CH), while the remaining nodes serve as Cluster Members (CM) in the network. The procedure optimally used the quantity of CH in the network. The Cluster head(s) aggregated the data and transmitted the data to the BS. The simulation result shows that the proposed protocol improved system performance and prolonged network lifetime.
