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.
