Abstract: We first study the various routing strategies for Mobile Ad Hoc Networks (MANETs). In general, on-demand protocols achieve better and more stable performance compared to table-driven protocols especially at high mobility due to their efficient utilization of control overhead.We next introduce AODV-RR (Ad Hoc On-demand Distance Vector Protocol with Redundant Routes) with improved robustness by incorporating route redundancy into AODV. The use of redundant routes provides immediate alternative routes to salvage time-critical traffic flows upon link failures, hence increasing overall throughput and shortening delay.Lastly we experiment further improving performance by making Route Expiry Timeout (RET) adaptive to mobility. Adaptive RET proactively prevents aging of routes especially at higher mobility and hence helps reduce the chances of using potentially stale routes. Our investigation suggests that by selecting optimal RET values depending on mobility, substantial performance gain can be achieved at affordable increase in control overhead.
