Performance analysis of energy aware routing schemes under various mobility models

In Mobile Ad hoc Networks (MANETs) nodes are free to move arbitrarily with different speeds, which makes the network topology change randomly and unpredictably. The mobility models give the movement pattern of the nodes w.r.t. their direction, location and speed over time. Some of these models depict real life scenarios. This paper analyses the energy consumption of our previous proposed energy efficient algorithms viz. energy aware AODV (EA-AODV) and Optimized Energy Aware Routing (OEAR) scheme, under various mobility models. The mobility models considered in the paper are random walk, random waypoint, column based, reference point group mobility model. Simulation results obtained in NS2.34 show that OEAR has better energy consumption.
