Research On Routing Protocols In Ad Hoc Networks

Ad hoc is composed of the temporary multihop autonomous system with the mobile terminal of radio module. The mobile terminal with the function of routing can make up of any topology network. The network can work independently or work with Internet and cell wireless network. In Ad hoc, every mobile terminal has the function of host or router. Ad hoc has the characteristics of mobile communication and computer network. It can be a special mobile network.Normal routing protocol is designed for fixed network. The structure of it is almost changeless. In Ad hoc, the structure of topology changed quickly and randomly, because the nodes move randomly. With normal routing protocol, the rebuilding of routings can waste many resource when the structure of topology changes. Therefore, routing protocol is one of the important and challenging issues.The dissertation studied AODV routing protocols in detail. In the text, we put forward one new Ad Hoc routing protocol. This protocol is a method of improvement AODV routing protocol, which integrates surplus existing time and load of a node. Simulation results show that the new method improve Ad Hoc network performances, and increase throughput of nodes, and decrease the average delay.
