Finding a Stable Route Through AODV by Using Route Fragility Coefficient as Metric

The widespread applications of mobile ad hoc networks (MANET) and scarce network resources have lead to the development of many protocols in this field. The need of time is to find a protocol which makes efficient use of resources and improves the overall performance of the network. This paper focuses on enhancing the performance of ad hoc on demand distance vector (AODV) routing protocol by choosing route fragility coefficient (RFC) as its metric. This metric causes AODV to find a stable route. The stable route is characterized as the one which has less dynamism and in which nodes stay close to each other. Simulation results are provided to demonstrate the improvement in throughput and reduction in routing protocol overhead with increased mobility. The performance metrics are measured by varying the maximum speed of the nodes and size of the network
