摘要 针对近年来无线传感器网络所设计的MAC协议从不同角度对S-MAC进行了改进,但均没有考虑周期性数据传输的特性这一问题,提出了基于时钟的媒介访问控制算法TB-MAC.TB-MAC根据对流量的预测和节点的历史活跃信息来计算休眠/活动周期.仿真结果表明TB-MAC比S-MAC节省了至少75%的能耗,同时获得了优于S-MAC的延迟性能. The most recent MAC protocols for sensor networks improved S-MAC from different points of view other than periodic data transmission situation. A time-based medium access control algorithm TB-MAC was presented specifically for periodic transmission applications. Based on the traffic forecasting and the time interval during which each node needed to be active previously, TB-MAC could compute the sleep/wakeup schedule. Simulation result shows that, in comparison with S-MAC, TB-MAC has enhanced energy efficiency by at least 750%, achieving at the same time better delay capability than S-MAC.
