Broadcasting also called as flooding is one of the earliest research interests in mobile ad hoc networking. The main objective of broadcasting scheme is to avoid broadcast storm problem, provide good network performance and scalability. Existing probabilistic scheme consider only one parameter such as network density, node location or counter value in calculating probability value for broadcasting. These probability scheme cannot change their broadcasting approach even though the objectives of the system may change based on node characteristics or network conditions. There is no probabilistic broadcasting schemes which consider multiple parameters for determining the probability to broadcast. The parameters that greatly affect broadcasting is the network density, node location, etc. in this paper a new probabilistic broadcasting algorithm has been proposed that aims to utilize up to date local topological characteristics of intermediate nodes such as network density and node location. As we are using multiple values to calculate probability for broadcasting there is a need of optimization technique (such as Fuzzy Logic). With the use of fuzzy logic the proposed algorithm can keep good balance between rebroadcast efficiency, reachability and throughput.
