A new multipath routing protocol for Ad Hoc network

Mobile Ad Hoc networks consist of a collection of wireless mobile nodes which dynamically exchange data without reliance on a _xed base station or a wired backbone network, which makes routing is a crucial issue for the design of Ad Hoc networks. In this paper, we discussed a hybrid multipath routing protocol named MP-OLSR. It is based on the link state algorithm and employs periodic exchange of messages to maintain topology information of the networks. In the mean time, it updates the routing table in an on-demand scheme and forwards the packets in multiple paths which have been determined by the source. If a link failure is detected, the algorithm recovers the route automatically. The simulation in NS2 shows that the new protocol can e_ectively improve the performance of the networks. ©2012 by Binary Information Press.
