摘      要：Wireless sensor network （WSN） is a data-centric intelligent monitoring system and data transmission is the routine *** the communication resource of WSN is very limited is most pivotal function,communication reliability becomes one of the most pivotal ***,the lack of wireless link and the loss of data make the study of communication reliability *** solve these problems,a nodes cooperation based multi-path transmission protocol （NCMPT） is proposed in this *** this protocol,network is divided into several hierarchy areas,and a clustering construction mechanism is studied to take the amount of nodes in each clustering to meet the requirement of reliable *** this basis,the selection strategy of optimal intermediate node is ***,a supporting data relay clustering of nodes is constructed,and the nodes cooperation based data synchronized reception scheme and asynchronized competition relaying scheme is studied to enables the end-to-end data transmission to be more reliable and *** testify the performance of proposed protocol,a simulation experiment is designed,and the results show the proposed protocol can get improvement in communication reliability and time-delay.
