Research On The Routing Protocols Of Wireless Mobile Ad Hoc Network

With the continous development and widely application of wireless telecommunicationtechnology in different areas, Users gradually require higher quality of its service. Because of thelimitation of wire network and mobile IP network, Ad Hoc network gains widely attention recently.Ad Hoc network doesn’t rely on any basic facilities and can achieve fast communication in time.These features make Ad Hoc network use in many special environments, such as: Battlefield,frequent seismic zone and so on.Firstly, this paper gives an introduction of the basic conception and classification of Ad Hocnetwork. Then it gives a detailed analysis and instruction of the typical protocols for different typeof Ad Hoc network. Based on the above, we propose the research emphasis of the paper----researchon the protocol of mobile network and wireless sensor network. Meanwhile, it also gives a briefintroduction of the key technique and idea which may be used in the paper.Secondly, it is mainly about the detailed analysis and research on typical protocol of mobile AdHoc network—AODV. On the basis of this analysis, we propose the weaknesses of the protocol andthen lead into related key techniques and solution. With all the above, we can accomplish a newprotocol named QoS-MAODV. It adopts multiple paths to transmit information. When choosing thebest paths for transmitting, it takes many factors into account. Such as: the available bandwidthresource and mutual influence among nodes. From the simulation result of NS, we can see whencomparing with AODV, QoS-MAODV can greatly reduce the end-to-end time delay, enhance thedelivery rate of packets and extend the lifetime of network.Finally, this paper does a detailed analysis and research on the typical protocol of WSN(wireless sensor network). Because of the emergence of bandwidth resource, power-less of nodesand the shortcoming of DD, we adopt network coding and QoS-aware method to design a newrouting protocol—NCQ-DD. This new protocol can greatly enhance the transmission efficiency. Itchooses transmission paths which need lower energy consumption and offer more availablebandwidth. In this way, the energy consumption of network can be greatly lower and the energybalance can be realized. The work of the wireless sensor network can be very efficiency.
