Research On LMRP Based On Mobile Ad Hoc Network

MANET network is a kind of self-organized and self-adaptive wireless network, which has great prospect in military and civil application. MANET is a kind of network in which each node works as a communication terminal and a router. For the reason of the restriction of the indefiniteness of network topology and the limitation of wireless medium bandwidth, the research in router protocols in MANET is important and significant.Firstly, the paper studies the router algorithms and router protocols in MANET. Secondly, it proposes the"mixed route protocol LMRP"adaptive in dynamic and complicated environment, which cuts in the design of unicast with multipul notes'reply, based on the summarization and analyses of the technology and performance used in MANET. Thirdly, the thesis introduces the complete design plan of this protocol, including method design, specific design, data structure in LMRP, router discovery algorithm, router maintenance protocal, router optimization protocal, logistic layered method, MTU solution, robusticity policy, etc.Finally, the thesis simulate protocals in LMRP and compare it with AODV by OPNET emulator,which shows that the protocol has advantages in several domains, including end-to-end delay, throughput, etc.
