针对无线传感器网络结点体积小、内存与计算能力小、靠电池供电、结点密度高以及网络规模大的特点,提出了高效广播协议(EBP,Effective Broadcast Protocol).通过对广播过程中一个结点转播之后其邻域内其它结点的转播,即引发新转播的讨论,完成了对最佳引发新转播的分析.EBP广播协议以此为依据选择转播结点,不需要任何邻结点信息就可以高效完成广播,算法的控制开销和存储开销大大降低.EBP广播机制简单有效,在无线传感器网络中具有良好的扩展性.

Wireless sensor network is featured by small node size and memory, low computing capability, battery supplied energy,high node density and huge network scale. In view of the above features of wireless sensor network, an effective broadcast protocol (EBP) is presented in this paper.In the discussion on the induced rehroadcast of a node's rebroadcast, the optimized induced rebroadcast are analyzed. In EBP,optimized rebroadcast nodes are selected based on the above analysis results and each node need not any neighbor information to complete a broadcast efficiently. Thus,the control and memory overheads are reduced greatly. The simple and effective EBP algorithm performs well in wireless sensor network.
