Industrial wireless deterministic communication based on WLAN: Design, implementation and analysis

In this article, it presents the status of wireless communication being applied in industrial environment, and points out its deterministic communication issue existed in control network. According to this issue, a kind of industrial wireless deterministic communication mechanism and method based on WLAN is put forward. Afterwards, the main part is to describe the process of design, implementation and test programs. Depending on test results, some analysis is set out to indicate that the parameters performance of IWLAN with deterministic scheduling mechanism is better than commercial WLAN. At the end of this article, simulation result is supplied as the reference of actual IWLAN parameters performance.
