Multipath Routing for Mobile Ad Hoc Network

Multipath routing allows the establishment of multiple paths between a pair of source and destination node in mobile ad hoc network. It is typically proposed in order to increase the reliability of data transmission or to provide load balancing and has received more and more attentions. In this paper, we present a multipath source routing protocol with some QoS guarantee. During the routing discovery, the source node firstly checks whether it has the routing information to the destination node. If not, it begins to broadcast RREQs to its neighborhoods and finally to the destination. From the received RREQs, the destination node can construct a certain topology for network and the path that is maximally disjoint from the shortest delay path is selected as our desirable routing. Simulation results show that comparing with traditional unipath routing scheme, the proposed protocol can greatly increases the packet delivery rate and extend the life-span of network.
