In a multi-hop mobile ad-hoc network, broadcasting is an elementary operation to support many applications. Broadcasting by flooding may cause serious redundancy, contention, and collision in the network, which is referred to as the broadcast storm problem. Many broadcasting schemes have been proposed to give better performance than simple flooding in mobile ad-hoc network. How to decide whether rebroadcast or not also poses a dilemma between reachability and efficiency under different host densities. In this paper, we propose an enhanced broadcasting scheme, which can reduce rebroadcast packets without loss of reachability. Simulation results show that the proposed scheme offers better reachability and efficiency than other previous schemes.
