Cluster and Grid Based Performance Evaluation on Energy Consumption for IEEE 802.15.4/Zigbee Wireless Sensor Network

Wireless sensor network is mainly used for real time applications which raise fundamental problems. These problems are like limited energy resources and replacement task. Therefore good functioning of such networks depends on energies of nodes. In this paper we have introduced analytical model which predict the energy consumption. We have also compared two different formats of nodes which are organized as cluster based and grid based. We have used new existing tool for simulation analysis QualNet.
