| 摘 要： | 为了使无线传感器网络移动节点加入时能快速地建立连接并且能量消耗较低,提出一种动态、节能的信道接入控制协议DEE-MAC.该协议以一种新颖的方式在TDMA的基础上叠加了动态分簇和优先级竞争簇头机制,在移动和静止场景中,既有最低性能保障,又有较高信道利用率.仿真结果表明,有移动节点加入时,DEE-MAC协议在数据吞吐量、延时以及丢包率方面比SMAC协议都有明显改善.

| Abstract: | In order to consume less energy and set up connection with mobile nodes timely,a dynamic,energy-efficient MAC protocol(DEE-MAC)for mobile sensor networks is presented.The DEE-MAC protocol is a TDMA-based protocol with forming cluster and CSMA mechanism.It can provide finite delay guarantee and improve channel utility rate.The results of simulation show that the DEE-MAC protocol performs better than the existing SMAC protocol in terms of throughput,end-to-end delay and drop data packets in scenarios involving mobile sensors. |
