Research of the Network Manager for WIA-PA

WIA-PA is a standard of wireless networks for industrial-process automation, which is proposed by Industrial Wireless Alliance of China. Network manager is an integral role of the WIA-PA network. In this paper, we first look closely into the architecture of WIA-PA and the responsibility of network manager. More specifically, we set our focus on the schemes and algorithms involved in the process of topology maintenance, routing configuration and communication resources allocation, which are the core responsibilities of the network manager. Finally, with Visual Studio .NET the paper has implemented the network manager of WIA-PA which has been running for a long time in the laboratory. The results show the network manager can effectively utilize channels and timeslots resources, optimize resource allocation and improve the overall WIA-PA performance.
