The appropriate use of probabilistic broadcasting can reduce the number of packet transmission, effectively alleviating the problem of contention. In particular, a good probabilistic broadcast protocol can achieve higher saved rebroadcast and higher reachability. This paper presents a new probabilistic approach that dynamically adjusts the rebroadcasting probability as per the node distribution and node movement. This is done based on locally available information and without requiring any assistance of distance measurements or exact location determination devices. We evaluate the performance of our approach by comparing it with simple flooding as well as a fixed probabilistic approach. The results show that the new algorithm exhibits superior performance in terms of both the reachability and saved rebroadcasts.</ABSTRACT></RECORD></RECORDS></XML>
