As technology is enhanced different MANET devices are introduced with more mobility which in turn consumes more battery power. Energy optimisation is a basic necessity to evaluate the battery power consumption in the MANET networks. In previous research some energy efficient protocols like EPAR, MTPR etc are already available which reduces battery power consumption up to 20% only. Still there is a limitation of energy efficiency. EPAR Protocol reduces power consumption by selecting routes with

... ore packet capacity and less energy consuming. We introduce the proposed EPAR Protocol which reduces power consumption up to 40% and increases the network lifetime. EPAR protocol has the limitation of network rescanning during link failure. Therefore proposed EPAR with implementation of Adaptive Ant colony optimization is introduced which provides alternative path in case of link failure. Proposed EPAR protocol gives better results for every parameter like delay, throughput, network load, jitter etc. Power saving is the urgent need of mobile adhoc networks to scale back gap between the power consumption needs and power accessibility.
