The Self-fited Energy Routing Protocol Study Of The Mobil Ad Hoc Network

The network nodes mainly depend on battery-powered in the Ad hoc network, so their energy are limited. Without the node's energy, it is easy to make some node to be the central ones, and furthermore, make these nodes lose their function in a early stage and effect the whole network.This master's degree essay gives a study on the problem of the mobile Ad hoc network's IP routing, and compares some typical IP protocols. The importance is to make a deeper analysis and study on the AODV IP routing protocol, and to promote a Energy and load Adaptive routing—ELAR, which is based on the surplus energy and the load capacity. To find a arithmetic which take into account the largest load capacity and the smallest total energy consumption of the network, which is NP-complete problem, therefore, can only focus on a particular aspect, taking into account the overall balance performance. ELAR is a compromising algorithm, namely giving consideration to the QoS support of different business and could balance the energy consumption. Through setting up an emulation model, it uses the network's emulation device NS-2 to emulate the algorithm. The result of the experiment has verified that algorithm could meet the transmit demand of different business and balance the knot energy consumption of the whole network. What's more, it can extend the effectual working period of the network.
