Abstract: The industrial wireless network is widely utilized in factories based on TDMA technology．This paper proposed a novel fast parallel networking to ameliorate the funnel effect which can slow down the network efficiency during the WIA-PA industrial wireless process．It can not only achieve a parallel network of the routing device,but also reduce the communication collision to avoid resource conflicts by transforming superframe structure,selecting the initial time based on the residual energy,linking status and starting time,as well as improving the resource allocation algorithm in the joining process．The experimental results illustrate that this algorithm plays an important role in enhancing the networking efficiency greatly,and shortening the networking period significantly.
