Performance Investigation of Signal Strength based Gossip AODV

Due to their "on demand" nature, the reactive protocols for MANETs, incurred less overhead and hence are preferred over proactive protocols. Since reactive protocols rely on network wide flooding of routing messages, they suffer from the "broadcast storm" problem. Received signal strength based probabilistic flooding scheme named RSS-GossipAODV was proposed in [13]as an attempt to solve the frequent link breakages and broadcast storm experienced in AODV routing protocol. This paper investigates the ability of RSS-GossipAODV to handle different node mobility speeds in faded and non-faded environments. The performance of RSS-GossipAODV is evaluated by varying node mobility speed. It is evident from our experimental results that in both non faded and Rician faded scenarios, RSS-GossipAODV outperforms conventional AODV in term of packet delivery ratio, throughput, delay and link breakages and at the same time tries to minimize the broadcast storm problem by flooding lesser number of route request (RREQ) messages.
