Abstract
Current wireless technologies for industrial applications, such as WirelessHART and ISA100.11a, use a centralized management approach where a central network manager handles the requirements of the static network. However, such a centralized approach has several drawbacks. For example, it cannot cope with dynamicity/disturbance in large-scale networks in a real-time manner and it incurs a high communication overhead and latency for exchanging management traffic. In this paper, we therefore propose a distributed network management scheme, D-MSR. It enables the network devices to join the network, schedule their communications, establish end-to-end connections by reserving the communication resources for addressing real-time requirements, and cope with network dynamicity (e.g., node/edge failures) in a distributed manner. According to our knowledge, this is the first distributed management scheme based on IEEE 802.15.4e standard, which guides the nodes in different phases from joining until publishing their sensor data in the network. We demonstrate via simulation that D-MSR can address real-time and reliable communication as well as the high throughput requirements of industrial automation wireless networks, while also achieving higher efficiency in network management than WirelessHART, in terms of delay and overhead.
Highlights
Industrial control applications can be categorized into two main classes: (i) factory automation, and (ii) process control
This paper presents a Distributed Management Scheme for Real-time applications (D-MSR) that is built for wireless industrial automation
D-MSR s5 and WirelessHART s1 provide more reliability in coping with internal interference in case of different interference ranges. This is because D-MSR s5 combines the retransmission by virtual link method, while WirelessHART s1 avoids the spatial reuse of communication resources
Summary
Industrial control applications can be categorized into two main classes: (i) factory automation, and (ii) process control. This paper will address the (i) real-time and (ii) reliable communication requirements of periodic monitoring and process control applications from class 1 to 5 in industrial harsh and dynamic environments. Those applications generally involve mostly static field devices (i.e., sensors and actuators). D-MSR could address the issues of high throughput and reliable communication as well as real-time requirements, while achieving higher efficiency in network management in terms of delay and overhead.
