“…The first one is the dependence of the timeslot allocation for sensors and actuators [5]. From the control loop point of view, a sensor needs to be scheduled first to send the measurement value to the controller, then after execution, the command is transmitted to the actuator for reaction.…”

Abstract-Applying Industrial Wireless Sensor and Actuator Networks (IWSANs) in the industrial automation is a growing trend due to flexibility, mobility and low cost. According to the current standards, such as WirelessHART and ISA100.11a, multichannel TDMA transmission is included for reliable and deterministic communication. In this paper, we clarify the dependence of TDMA scheduling for sensors and actuators and point out the low correlation between the scheduling delay and the overall quality of control, and focus on reducing jitter in scheduling for improving quality of control and system stability. We propose a scheduling algorithm, aiming for lowing jitter and compare it with two traditional real-time scheduling schemes. Our simulation results exhibit significantly lower jitters by applying our scheduling policy than those two traditional scheduling schemes.

“…If needed, each device further has a unique downlink graph from the Network Manager for forwarding specific control messages to itself. Although several research works have been devoted on the design of data link layer scheduling in WirelessHART networks [8], [13], [14], [15], how to satisfy the enforced strict reliability requirements on the routing graphs and construct data link layer communication schedules on top of them is still a challenging problem and has not received sufficient attentions.…”

Abstract-Industrial wireless mesh networks are deployed in harsh and noisy environments for process measurement and control applications. Compared with wireless community networks, they have more stringent requirements on communication reliability and real-time performance. Missing or delaying of the process data by the network may severely degrade the overall control performance. In this paper, we abstract the primary reliability requirements in typical wireless industrial process control applications and define three types of reliable routing graphs for different communication purposes. We present efficient algorithms to construct them and describe the recovery mechanisms. Data link layer communication schedules between devices are further generated based on these graphs to achieve end-to-end real-time performance. We have built a complete WirelessHART communication system and integrated our solutions into its Network Manager. We demonstrate through extensive experiment results that our algorithms can achieve highly reliable routing, improved communication latency and stable realtime communication in large-scale networks at the cost of modest overheads in device configuration.
