Node Deployment in Homogeneous and Heterogeneous Wireless Sensor Network

Optimal sensor deployment is necessary condition in homogeneous and heterogeneous wireless sensor network. Effective deployment of sensor nodes is a major point of concern as performance and lifetime of any WSN. Proposed sensor deployment in WSN explore every sensor node sends its data to the nearest sink node of the WSN. In addition to that system proposes a hexagonal cell based sensor deployment which leads to optimal sensor deployment for both homogeneous and heterogeneous sensor deployment. Wireless sensor networks are receiving significant concentration due to their potential applications ranging from surveillance to tracking domains. In limited communication range, a WSN is divided into several disconnected sub-graphs under certain conditions. We deploy sensor nodes at random locations so that it improves performance of the network.This paper aims to study, discuss and analyze various node deployment strategies and coverage problems for Homogeneous and Heterogeneous WSN.
