Review of Energy Conservation Approaches in MANET

Mobile adhoc network consists of collection of wireless mobile nodes dynamically forming a temporary network without the use of any pre existing network infrastructure or centralized administration.energy conservation is necessary due to increasing gap between the power consumption requirements and power availability.To maximiseadhoc networks lifetime traffic should be send through route that prevents the nodes with low energy. Main objective is to usevarious techniques such as energy efficient routing, power awareness and loaddistribution with respectiveof advantages and disadvantages.
