Abstract: In order to avoid Broadcast Storm, the Energy Adaptive flooding Broadcast (EAB) strategy is proposed. The algorithm is based on probability rebroadcast to reduce the number of rebroadcast. According the remain energy of the nodes，EAB decides which nodes need to rebroadcast to reduce the chance of contention and collision among neighboring nodes in the networks and restrain the flooding effectively. Analyses and simulations show that adaptive flooding broadcast strategy outperforms the ordinary flooding broadcast method and increases the reach ability in the Ad hoc networks.
