Mobile Ad hoc NETworks (MANET) very often suffer from route failures due to the mobility of nodes. This effects an ongoing data transmission resulting in pre-computed routes becoming invalid. So it is important for a routing protocol to recover from such failures by providing redundant paths which are robust. With this objective, this paper proposes a novel method to improve an on-demand routing Protocol AODV to store multiple paths which are also stable (PAOMDV). Further having found stable paths this protocol will detect diminishing signal strengths between the nodes and proactively switch to pre-discovered path thus avoiding costly route maintenance process. Simulation results show that this protocol has better end-to-end delay with lesser routing overhead and lesser packet drops.
