Improvement of AODV Protocol Based on Energy-Awareness

Ad Hoc network, a self-organization network system, can establish a communication to a plurality of mobile users without any infrastructure. All nodes in this type of network system exist via portable sources. The hot spot of Ad Hoc network is to realize further energy consumption reduction. In the work, an improved protocol, by which energy consumption is reduced, is proposed based on AODV protocol; named NL-AODV, it choose the optimal routing by the capacity, the nodes energy and the hop. It is verified that the improved protocol can effectively prolong the original lifetime of the network and obviously improve the routing efficiency by simulations. Consequently, it is more suitable for dynamic topology changes in the network system at present.
