摘要:
在无线传感器网络中,节点的业务负载是随网络节点的位置和网络运行的时间不断变化的,又由于每一个节点能量有限,功耗是无线传感器网络性能的重要参数之一。针对无线传感器网络的这些特点,对IEEE802.15.4MAC层协议的关键技术进行了阐述,讨论了CSMA/CA信道访问机制在动态自适应方面的不足,进而设计提出了一种基于动态自适应的低功耗退避算法-DA-CSMA/CA算法,最后对该算法进行了仿真分析。仿真结果表明,该算法在网络拓扑相对固定的环境中能在低功耗的前提下很好地适应网络流量的变化
Abstract:
In wireless sensor networks,service load of the network node was changing all the time with the node location and the time for network operations.Besides,because of low power capacity of each sensor node in wireless sensor networks,energy consumption was one of the important performance parameters in wireless sensor networks.In view of these characteristic of wireless sensor networks,carried on the detailed elaboration to the key technologies of MAC procotol of IEEE802.15.4,discussed the shortcomings of the CSMA/CA channel access mechanism in dynamic adaption.Then designed the low-power backoff algorithm based on dynamic adaption which called DA-CSMA/CA.The result of the final simulation of the algorithm shows that the algorithm can be well under the premise of low-power adaptive network flow rate changes in the certain network topology
