The WIA industrial wireless network which based on IEEE802.15.4 standard. The network will produce some network conflicts and data loss phenomenon with the expansion of network scope and the increasing of amount of data in the network. In view of this kind of phenomenon. This paper introduces a abinary exponential backoff algorithm. We establish experimental model to simulation analysis. We obtained simulation model under the condition of stable network. It can reduce the probability of collision between nodes when the node sends data packets to the other node.
