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.
