Role of relay node in Wireless Sensor Network: A survey

Abstract

This paper describes the concepts of Relay node characteristics, various deployment methods, and their internal behaviors in the Wireless Sensor Networks (WSN). First, the internal behavioral characteristics of relay node and their different state processing are analyzed using algorithm. Then, the influence of relay nodes in WSN and the potential relay node deployment methods were explored and with the efficient deployment of relay nodes, a simple research-level review of WSN accuracy and network energy consumptions are provided via Simulation results. Exposed research issues for the realization of relay node deployment in WSN were also discussed.
