| Ad hoc networks are self-organizing networks that can be organized anywhere and at anytime without the aid of or centralized administration. Due to this characteristic, the application of these networks is more and more wide.Such as disaster recovery, crowd control, search and rescue, and automated battlefields are typical examples of where ad hoc networks are deployed. And the structure of these networks is very simple, don't need any established network infrastructure.Ad hoc networks are self-organizing, multi-hop, topology dynamic-changed wireless networks.This particularity made it impossible that the technology of traditional wire networks were directly used in Ad hoc networks, due to this ,many new protocols and technologies are required for ad hoc networks, such as channel connection technology,safety and route technology and so on.This paper focuses on Ad hoc networks route technology,discusses multiroute among route technology as research direction.Ad hoc networks are summarized in chapter one, including the definition, characteristic,application fields and critical technologies of Ad hoc networks.The analysis of research actuality of network route technology and multiroute technology are conducted in chapter two,furthermore, relevant network Protocols are also comprised in it. In the third chapter of this article, we research Ad hoc route protocols and multiroute protocols.A new inproved DSR multiroute algorithm is addressed in the chapter four, including of a new separated multiroute algorithm that inproved on the basis of DSR.In the end of paper, the comparison of new algorithm and DSR multioute protocol are performed through end-to-end average delay, date package transmission ratio and date discard ratio as statistic parameter during the simulation.The result indicates that comparing the new algorithm with DSR multiroute protocol, the performance of end-to-end average delay and end-to-end throughput are improved distinctly without notable increased cost of route protocol. |
