In highly wireless mobile network, there are frequent partition (division) of network and change in topology. Some broadcasting protocols were developed to disseminate information across partition. The drawbacks of these protocols is that there are additional retransmissions whenever a node discovers a new neighbor. Therefore, a broadcasting protocol is proposed that will reduce transmission while maintaining a good reliability.The main novelty of the proposed method is not to act each time two nodes discover each other as new neighbors. Each node maintains a receiver list (RL) containing nodes that have received the message (up to 2-hop). When a node discovers a new neighbor, it checks whether the new node is in RL. If not, then it considers broadcasting. Otherwise, it does not broadcast. The proposed method and the existing methods by HBR, VO & CEM are implemented and compared. Simulation results showed that the proposed protocols produces less transmission than other methods and maintains a good reliability .
