Performance Analysis of Gateway based Multihop Routing Protocol in WSNs

Abstract

Hierarchical cluster based routing protocol is very famous in Wireless Sensor Networks (WSNs). In this, Cluster Heads (CHs) are chosen among the nodes in the cluster based on the random probability of each node in the network. In proposed protocol, the sensor network field is alienated into four logical regions on the basis of the position of sensor nodes. If the predefined distance is greater than sensor node’s distance then the data is directly forwarded to the BS and gateway. Otherwise the regions are alienated into clusters having a cluster head in each cluster for aggregate and forward the data to gateway which further forward the data to the base station. Cluster head voting in each region is based on the Energy Consumption Rate (ECR) of each node in the earlier round. Simulation results show that ECR based multihop routing protocol better than existing protocols such that LEACH, M-GEAR.
