An Efficient Energy-Saving Broadcast Mechanism for Wireless Sensor Networks
Wen Aijun · Dianzi xuebao · 2009
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 rebroadcast 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.
