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.
