The Research Of The Wireless Ad Hoc Network Routing Protocols Based On Energy

Wireless Ad Hoc network is a kind of mobile communication network which is rapid and dynamic. It is composed by a group of mobile terminal nodes. These nodes are usually powered-up by batteries and can act as not only mobile terminal but also a router. But the energy of the battery is limited, which will lead to the failure of the single node and also change the entire network performance and working hours. Therefore, routing protocol based on energy research is very important on the study of wireless Ad Hoc network.In this dissertation, we researched on wireless Ad Hoc network, discussed the basic structure of the Ad Hoc networks and analyzed some typical routing protocols in which the algorithm of AODV(Ad Hoc On-Demand Distance Vector Protocol) routing protocol is focused on. Also, the energy saving mechanism of wireless Ad Hoc network is discussed and analyzed which lay the foundation of further study on how to improve the property of the network.The routing protocol OP-AODV(Optimization Ad Hoc On-Demand Distance Vector Routing) based on the energy optimization strategy is proposed to deal with the problems in AODV, such as the limited energy of the node, the connection interrupted when the node is power off and so on. The OP-AODV has fully considered the residual energy of the node and represented the residual energy of node by hop counts, providing new determine parameters for the routing. Considered both the influence of the residual energy and the hop counts, the routing protocol OP-AODV can prolong the lifetime of the network and can also improve the performance of network. In the end, simulated in NS2 and compared with routing protocol of AODV, OP-AODV is verified to be correct and superior.
