基于网络编码的WSNs数据收集方法

无线传感器网络(WSNs)监测数据的收集方式方法是目前的研究热点,而无线传输的广播特性又使得网络编码非常适合于无线网络。在介绍网络编码原理、核心思想以及在WSNs应用现状的基础上,提出了一种基于部分网络编码的自适应WSNs数据收集方法,该方法针对簇网络拓扑结构,簇成员节点把网络编码数据发送给簇头节点,簇头节点利用随机网络编码的方式把数据传输到Sink节点。实验结果表明:该机制具有能耗较低和汇报数据较准确的特点。

Data collection method of WSNs based on network coding

Monitoring data collection method of wireless sensor networks(WSNs) is current research hotspot,and the radio characteristics of wireless transmission enables the network coding is very suitable for wireless network.The principle,core ideas,advantages of network coding and its present situation of application in WSNs are introduced,and an adaptive data collection method in WSNs based on partial network coding is put forward,aiming at cluster network topology structure,the cluster member nodes send network encoding data to cluster head node,and it sends to Sink node by random network coding mode.The experimental results show that this mechanism has characteristics of low energy consumption and accurate report data.
