Mobile Adhoc Networks (MANETs) permit mobile nodes to communicate devoid of any sustain of predetermined and federal network as it does not follow any preset network communications and all nodes are gratis to travel from one position to a further. Power consumption or energy constraints play an important role in the flow of information between nodes. In the dynamic topology of MANETs, energy or battery is a huge difficulty to keep the mobile node running for a long time. Any node can move from one position to another in a consistent manner, making it difficult to predict the movement of any node in a particular order. Due to this dynamic change in topology the route establishment and its maintenance becomes complicated. Hence energy utilization of the node is one of the parameters that may change the performance of MANETs. In this paper, simulation result based on AODV routing protocol with 50 random mobile nodes under file and random waypoint mobility models concerning generic, mica-motes and micaZ energy models have been analyzed. Simulation outcomes imply that the file mobility model exhibits superior preference over the random waypoint mobility models in generic, mica-motes and micaZ energy models
