GLCP: Grid-LEACH Clustering Protocol for Wireless Sensor Networks

Due to scarce battery power of Sensor Node(SNs) in Wireless Sensor Networks(WSN), number of energy efficient protocols has been proposed in literature. Clustering is energy efficient technique in which Sensor Nodes (SNs) are grouped into cluster and in every cluster, Cluster Head (CH) is responsible for transmitting aggregated data of its member SNs to Sink. In this paper we present Grid-LEACH protocol that implements LEACH protocol on grid-based network. Simulation results shows that Grid-LEACH protocol improve network lifetime in terms of overall energy consumption as compared to LEACH by reducing the number of transmitted packets to Base Station (BS).Main feature of Grid-LEACH protocol is that in case any grid left without CH then secondary CH is fixed for that grid.
