Abstract: The wireless sensor network technology has continued to develop and its application in industry has grown significantly. However, it is challenged by the evil environment in industry field. This paper first analyzed the wirelessHART protocol, and then merited the mechanism of wirelessHART to design the industrial wireless mesh protocol according to application demand. Following that, the modified routing algorithm and TDMA scheduling algorithm based on TSMP were presented. Finally, the simulation results and hardware realization demonstrated that this protocol is able to satisfy the demands of application to industry.
