Abstract:
In this paper, a new implementation of AODV, called AODV-ProbA, is presented that substitutes SF with the Probability-based Adaptive (ProbA) broadcast lgorithm. AODV-ProbA is compared against normal AODV and another proposed enhancement for AODV, called DP-AODV. An algorithmic comparison between AODV-ProbA and DP-AODV shows minor but critically important differences in the use of local density knowledge and adjustment of the probability threshold. The simulation results also confirm our hypothesis that AODV-ProbA performs considerably better than AODV and DP-AODV in highly mobile dense networks under moderate to heavy traffic load.
