Abstract

Multipath extension of ad hoc on-demand distance vector (AODV) protocol can provide reliable and adaptable routes in mobile ad hoc networks. In this paper, we propose an AODV-based acyclic multipath routing method, which uses a dynamic hop count to discover loop-free multipath routes. The advantage of our method is that it allows a node to add a route entry with a hop count that is larger than its current hop count. This increases the possibility to find more loop-free route backups. To evaluate the performance, we present the simulation at the end of the paper and compare it with ad hoc on-demand multipath distance vector (AOMDV) protocol and others.
