Abstract

Added delay strategy can be used to solve the broadcast storm problem of ordinary broadcast mechanism (OBM) and maximize network life-time. Available added delay strategies take into account the distance and/or the residual energy. In this paper, we propose a new added delay strategy--Maximum Life-time Localized Broadcast (ML2B). As the node's number of neighbors that have not received the broadcast message (we call it coverage degree) can better describe the coverage rate, ML2B takes the coverage degree rather than the distance into account. ML2B also takes the residual energy into account as other strategies do. ML2B only need one-hop neighbor information to find the coverage degree, so ML2B is a distributed protocol and the overhead is small. Simulation results show that, as compared with OBM, ML2B can save at least 50% rebroadcast, its maximum end-to-end delay is lower, its reachability is the same, and its network life-time is two times longer.
