A mobile ad-hoc network, which does not use a wired network and base station system, is composed of a group of mobile and wireless nodes. There are various types of restrictions. The biggest restriction is the confined energy of the batteries. If the network is divided into more than two, and one of the nodes consumes all the energy, that node can no longer participate in the network. In recent years, much research has been under taken to not only improve the energy storage but also to lengthen the networks lifetime. In this paper, we propose an enhanced AODV (Ad-hoc On-demand Distance Vector) routing protocol, which is modified to improve the networks lifetime in a mobile ad-hoc network. One improvement for the AODV protocol is to maximize the networks lifetime by applying an Energy Mean Value algorithm which considerate node energy-aware. We know the effectiveness of enhanced AODV compared with AODV using NS-2.
