Survey on Grid based Energy Efficient Routing Protocols in Wireless Sensor Networks

Abstract

Sensor nodes in Wireless sensor networks (WSN's) have limited energy, range, memory and computational power.In WSN, it is an important task to send measured data at regular intervals from an area of interest for time sensitive applications to a base station or sink for further processing to meet the enduser queries.For reducing energy consumption grid structure was used now-a-days.With the grid structure in place, query and data needs to be propagated to the grid points only.Since the sensor nodes have limited battery power, therefore, approaches have been proposed over the years to reduce energy consumption and to prolong network lifetimes.These approaches in WSN are called as Energy Efficient Routing (EER) protocols.In this paper, a comprehensive list of the grid based EER protocols have been studied with their relative advantages and disadvantages.
