A novel framework to provide reliable and timely communication for industrial control applications using wireless token passing approach

This paper investigates the strict reliable and timely requirements of the hard real traffic based control packets in the industrial control applications. As a result, a framework is proposed with two novel approaches intended to meet the strict deadline requirements and reliability requirements of the industrial control packets. The first novel approach, timed control panel incorporates timed token protocol to provide guaranteed channel access time to each station present in the wireless ring structure. The second novel approach, adaptive sub-MAC Hybrid Automatic Repeat Request (HARQ) reduces the packet error rate and the packet loss rate by reducing the size of MAC frame by half. The mathematical analysis and simulation results show that the proposed framework ensures in providing the reliable and timely communications for Industrial control applications.
