Wireless Ad Hoc Networks Energy Efficient Routing Protocol

Wireless Ad Hoc network is a kind of mobile wireless network with no infrastructure. It is composed of a series of mobile communication nodes. It has the distinction with wired network and centralized wireless network that no central node, multi-hop connection, auto-organization, energy limited, etc.Routing protocol research focuses on the point that how can a network node find a way from source node to its destination and transport information. Routing protocol in ad hoc has many differences compared with wired network and centralized wireless network. We must concern these differences when we design routing protocol in ad hoc. Routing protocol research has become the emphasis in ad hoc protocol stack designing.The thesis first simply introduced the current situation and future development of Wireless Ad hoc Networking, the basic conception, characteristics of the network, infrastructure of the network and a series of problems faced. And then, based on the network environment, we analyzed the mechanism of energy reserving and the method of cross-layer, and a new routing protocol that based on the flood restraining is proposed in chapter 4, then come into being CAODV(Cross-layer AODV Routing Protocol).In chapter 5, we put up simulation platform with OPNET, and realized CAODV routing protocol based on AODV, then compare with it. Simulation result indicated that CAODV protocol can achieve good performance at successful data packets sending, RREQ packets restraining, route setting time, overhead of protocol and energy consumption , all these can provide consult algorithm, model and data for design and planning of the real system.Finally, chapter 6 summarizes the dissertation, reviews the above research work and presents the future research directions.
