EEPSCZ: An Energy-Efficient Protocol with Static Clustering Zones

A wireless sensor network is a network system composed by a large number of communicating sensor nodes through wireless links. The main problem in wireless sensor networks is their constraints in terms of computational power, and thereafter for their energy consumption. In this work, we propose a new hierarchical routing protocol called Energy Efficient Protocol Static Clustering Zones (EEPSCZ) that aims to minimize energy consumption for wireless sensor network. EEPSCZ splits the network into layers; each layer is divided into a set of zones which forms the static clusters in order to eliminate the overhead caused by the dynamic clustering. EEPSCZ uses multi-hop between these different layers and utilizes temporary cluster heads to distribute the energy load of sensor nodes. We have conducted simulation to compare the performance of EEPSCZ with Energy Efficient Protocol with Static Clustering (EEPSC). Results show that EEPSCZ allows less amount energy consumption. It reduces the number of failed nodes, and therefore keeps more nodes alive after sending packets thus extends network lifetime.
