摘要
为了协调各节点的数据在同一信道中的传送,避免冲突。针对无线传感器网络的节点资源有限和网络拓扑动态变换的特点,本文提出了一种改进的MAC协议——ES-MAC(Energy effect-Medium Access Control,ES-MAC)协议。这种改进的协议利用动态的侦听睡眠周期既保证了系统性能,又节省了能量。仿真结果表明:ES-MAC协议不仅在网络性能方面比S-MAC协议、T-MAC协议有所提高,在节能方面也优于这二者。
To coordinate every nodes to send the information for avoiding collision.As the characteristic such as limited source and dynamic topology in WSN,the paper proposed A Improved MAC protocol,which used the dynamic listening/sleeping periods for assuring system performance and energy saving.The simulation shows that the ES-MAC protocol not only has a best system performance but also saving most energy than S-MAC protocol and T-MAC protocol.
