This paper provides an overview of MANETs and discusses how energy is one of the most
important constraints for these types of networks. The objective of the proposed work is to
develop an energy efficient AODV routing algorithm in a way which allows researchers to
choose the most appropriate routing algorithm. We have also simulated our work by using
network simulator and result shows that our proposed model always performs better than
AODV. We can also extend this work proposing more efficient methods as well as can be
implemented this work on sensor network. As a global conclusion we could also state that
current energy constrained protocols may need some tuning to minimize the power cost of
network interface. As we saw, the cost of energy consumption in sending packets can be
significant to the cost of being idle, but application and transport level considerations can make
the idle cost the dominant cost. Several protocols that put down a mobile receiver idle without
need wastes power.
