A robust routing protocol for wireless mobile ad hoc networks
Quan Wang, Wai‐Choong Wong · 2003
We first explore route redundancy mechanisms as means to minimize route discovery latencies of MANET protocols. We propose a new scheme AODV-RR (Ad Hoc On-demand Distance Vector Protocol with Redundant Routes) with improved robustness. The presence of redundant routes allows provision of immediate alternative routes to salvage time-critical traffic flows upon link failures. hence increasing throughput and minimizing delay. Further improvements are obtained by adapting Route Expiry Timeout (RET) to mobility at the expense of slight increase in overhead.
