An Adaptive Link-Disjoint Multipath Routing in Ad Hoc Networks


Article Preview

Mobile Ad Hoc Networks (MANET) are different from other network features, every mobile node possesses the role of host and router which makes routing mechanism become a key of the influence network stability. Because MANET topology is dynamic and easy-changing, so many scholars provide multipath and backup path routing protocol to solve the problems above. In 2001, Marina and Das proposed AOMDV multipath routing protocol which solves the limit of AODV single path routing protocol and promoted the efficiency of the whole network operation. However, we find out AOMDV has more than one first hop problem that cannot operate the multiple paths in some sparse networks. Thus, this paper uses the idea of common link to solve the problem which is an adaptive and efficient multipath routing protocol. To correspond to different dynamic topology, we need to adjust to route establishing scheme, in order to efficiently increase the number of paths and to decrease the frequency of route discovery which will provide a stable network connection. Finally, through the NS-2 simulation of experimental results shows our scheme the better performance in end to end delay and package delivery rate, compared with AOMDV routing protocol, and our scheme does not cause the additional network overhead.
