New energy model: Prolonging the lifetime of Ad-hoc On-Demand Distance Vector Routing Protocols (AODV)

Wireless Ad hoc networks have become a center of research interest over the last few years due to the promise of being self-configurable networks. One critical issue for almost all kinds of portable devices supported by battery power is energy conservation. Without power, any mobile device will become useless. This paper discusses new energy model that prolongs the lifetime of Ad-hoc On-Demand Distance Vector Routing Protocols which are modified to improve the networks lifetime in MANETs. There are two main ideas of energy-saving routing algorithm for Ad hoc routing protocols: The first one is to send each packet with minimum energy-consumption. The second is to maximize the network lifetime as much as possible. According to energy, the shortest path may not be the best path. A new mechanism of energy-aware named EA_AODV is proposed in this paper, which is based on the classical AODV.
