Multiprocessor scheduling meets the industrial wireless: A brief review

This survey covers the schedulability analysis approaches that have recently been proposed for multi-hop and multi-channel wireless sensor and actuator networks in the industrial control process domain. It reviews the noticeable results with a focus on IEC 62591 (WirelessHART) and ANSI/ISA100.11a-2011 (ISA100.11a), the two major wireless standards in the process automation industry. The paper addresses the mapping of multi-channel transmission scheduling to multiprocessor scheduling theory, and recognizes this mapping as a key research direction. It also provides a taxonomy of the existing approaches and discusses the main features and recent evolutions. The survey identifies a number of open issues, key research challenges, and promising future directions.
