Despite its simplicity, it can result in high redundant retransmission, contention and collision in the network, a phenomenon referred to as broadcast storm problem. Several probabilistic approaches have been proposed to mitigate this problem inherent with flooding. However, majority of these schemes uses fixed rebroadcast probability which is quite unlikely to be optimal in other simulation set up. In this paper, we propose a rebroadcast probability function which takes into account key simulation parameters like network topology size, transmission range and number of nodes in the network in determining appropriate rebroadcast probability for a given node. Simulation results reveal that this simple adaptation achieves superior performance in terms of saved-rebroadcast, number of retransmission node and end to end delay, without sacrificing reachability in dense network</ABSTRACT></RECORD></RECORDS></XML>
