| A mobile Ad hoc network (MANET) is a multi-hop, decentralized, self-configuring, peer-to-peer communication network that consists of several nodes with radio transceiver. It can be rapidly deployed and networking adaptively without relying on the pre-existing network infrastructure. The nodes in a MANET can dynamically join and leave the network without warning, and possibly without disruption to other nodes'communication.One of the important research areas of MANET is routing protocol. While every node have a role of terminal to receive and send messages, it is also a relaying node to retransmit messages. Because of the characteristic of Ad hoc network, the routing choosing will infect the network throughput, end to end delay, terminal nodes energy consuming straightly. Most terminal nodes have a model of finity energy, so the rest energy is the invaluable resource of nodes. Once resource exhausts, the terminal nodes can't work normally and be the retransmission node. At the same time, other nodes have overmuch rest energy, which makes inequity of energy consuming in Ad hoc network. Because many nodes play a more important action than other nodes, it will make large loss once energy exhausting.So it needs on the base of mini-path routing protocol, consider equity of energy consuming much. The objective of the article research is on the base of existing protocol, considering equity of network, making the network life time longer, improving the throughput.This thesis adopts OPNET networking emluation software, builds the service model, emluates and analyse the performance of AODV,DSR and more, and makes comparison to them. The results of emluation indicate the modified routing protocol can improve the networking equity in some entironment, making the network life time longer, improving the throughput, make index get to the needed.The conclusions in this thesis drawn from simulations indicate the superiority of new routing protocol, which offers the referrence for the... |
