摘要
给出了有效的应用于无线Ad Hoc网络的分布式节能广播算法。在确定转播结点时,该算法让那些拥有较多未覆盖邻结点和较大新增覆盖面积的结点进行转播,选取尽可能少的邻结点为转播结点,以减小广播分组在网络中的重复。所提广播算法的分布式设计解决了其他节能广播算法中存在的开销太大的问题,使其更加适用于无线Ad Hoc网络的特殊环境。通过大量的仿真对广播算法的性能进行分析,结果表明与其他算法相比,所提算法能够大幅降低转播冗余、有效增加网络寿命。
An efficient broadcast distributed energy-saving broadcast algorithm for ad hoc network was proposed. With the aim of selecting as less rebroadcast nodes as possible, it chooses nodes with more uncovered neighbors and with larger new coverage area to do rebroadcast, thus reducing the redundant rebroadeasted packets in the network. The distributed design determines the little overhead, which is applicable in the special wireless environment of wireless ad hoc networks. Simulation results show that compared with other algorithms, the proposed broadcast algorithm is capable of saving more rebroadcasts and obtaining longer useful network life-time under all circumstances.
