摘要

This paper compares the performance of on-demand Directional Node-Disjoint Multipath Routing (DNDMR) protocol with those of contemporary wireless ad hoc network routing protocols. DNDMR protocol especially performs well for grid-style network topology. Multipath routing inherently allows the establishment of multiple routes between source and destination. The important features of DNDMR are path accumulation with a novel directional method, reducing routing overhead by controlled propagation, and ensuring node-disjoint paths automatically. DNDMR improves the reliability of data communication (i.e., fault tolerance) over the wireless ad hoc network. It significantly reduces control traffic overhead and end-to-end delay, and improves throughput. We evaluate the comparative performance of DNDMR using ns-2 simulator. The performance is measured comparative to existing unipath routing (DSDV, DSR, AODV), and multipath routing (AOMDV) protocols. The simulation results reveal that DNDMR has better performance and more reliable than the contemporary unipath and multipath routing protocols.
