An on-demand node-disjoint multipath routing protocol is proposed to overcome the shortcomings of on-demand unipath routing protocols like AODV and DSR. The protocol has two novel aspects compared to the other on-demand multipath protocols: it reduces routing overhead dramatically and achieves multiple node-disjoint routing paths. Simulation results show that the proposed protocol achieves lower data delay and control overhead as well as higher packet delivery ratio.
