Wireless Sensor Networks (WSN’s) have gained a considerable importance and are used for a variety of applications. In WSN, an arrangement of sensor nodes is done to sense and collect information from its nearby environment and to send it back to the base station using routing protocol. The biggest challenges are how to handle the routing problems and to optimize the energy consumption in WSN. In this paper, performance evaluation of three energy models, Generic, Micaz and Micamotes, is presented using Ad-Hoc On demand Distance Vector (AODV) routing protocol. The performance evaluation is done using several parameters: Throughput, Jitter, Average End-to-End Delay (AEED), Total Packets Received (TPR) and Energy consumption in
three modes (transmit, receive and idle). Based on the evaluation, it has been found that Micamotes energy model using AODV routing protocol consumes less energy by 80.46% and 428.57% in transmit mode , 102.94% and 335.6% in receive mode from Micaz and Generic energy models, respectively.
