摘　　要：为了提高无线多跳网络中支持可靠广播/组播MAC协议的效率和灵活性,分析了可靠广播/组播的不同实现方式,以广播/组播代价为指标建立了有确认广播、有确认单播、混合方式三种实现方式的数学模型,并在此基础上提出了一种自适应可靠广播/组播MAC协议。该协议能够根据网络环境、业务特性等参数自动地选择效率最高的广播/组播实现方式。仿真结果说明该协议在效率与可靠性两方面均能达到良好的性能。To improve the efficiency and flexibleness of reliable broadcast/multicast MAC protocol in wireless multi-hop network, a novel efficient adaptive reliable broadcast/multicast MAC protocol was brought forward. The idea of design came into being based on the broadcast/multicast cost function, which was proposed by analyzing different realizations of reliable broadcast/multicast. According to the fimction, the protocol could select adaptively the optimal realization in various scenarios. Extensive analysis and simulation results validate the reliability and efficiency of it.
