Partial-Disjoint Multipath Routing for Wireless Ad-hoc Networks

On-demand multipath routing in wireless ad-hoc networks can be effective in achieving load balancing over the network and in providing a degree of resilience to route failures. A shortest multipath source routing (SMS) protocol is proposed - a multipath extension to DSR - supporting multimedia applications. The protocol has two novel aspects compared to other on-demand multipath routing protocols: it achieves shorter multiple partial-disjoint paths and allows rapid recovery of route breaks. Simulation results show that SMS outperforms the competing protocols with respect to a number of key performance metrics.
