【Abstract】Dynamic Source Routing(DSR) and Ad Hoc On-demand Distance Vector routing(AODV) protocols are most typical single-path routing
protocols, which support mobile node, self-organization and self-configuration network. The multi-path variants of DSR and AODV are extension of
DSR and AODV. This paper compares performance of multi-path variants in hybrid wireless Mesh networks and mobile Ad Hoc networks by
simulation. Result shows that, multi-path variants based on hybrid wireless Mesh networks have such feature as more higher packet delivery ratio,
more lower end-to-end average latency and routing overhead. The multi-path version of DSR can be applied to highly mobility environment due to
prominent improvement of performance under dynamic network environment.
