The research and implementation of wireless mesh protocol in industry

With its application in industry, the wireless technology need to satisfy the higher demand in harsh industrial environment. This paper first analyzed the WirelessHART protocol, and then it merited the mechanism of WirelessHART to design wireless mesh protocol in industry according to application demand. Following that, the modified Dijkstra´s algorithm was presented on the basis of graph routing. Finally, the feasibility of this protocol and the real-time implementation of the algorithm were verified by simulating in OMNeT++, so this protocol can meet the demand of time deterministic for industry application.
