Abstract :
Wireless Sensor Networks (WSN) consist of thousands of low-cost sensor nodes that are densely deployed. Broadcasting is a method that allows nodes in WSN to share their data efficiently. Due to the limited energy supply of each sensor node, it has become a crucial issue to maximize the network life-time in the design of broadcast protocols. In this paper, we propose an efficient broadcast protocol-Maximum Life-time Broadcast (MLB) for WSN. It optimizes broadcasting by reducing redundant rebroadcasts and balancing the energy consumption among all nodes. MLB uses the number of neighbors that have not yet received the broadcast packet to measure a node´s rebroadcast efficiency. High efficient rebroadcasts will help to reduce the number of rebroadcasts and thus reduce the broadcast overhead of MLB. Simulation results show that MLB can prolong the network life-time of WSN effectively and it is scalable with respect to network size and node density.
