In industrial environments various events can concurrently occur and may require different quality of service (QoS) provision based on different priority levels. To reduce the chances of collision and to improve efficiency in multi-event occurrence, Carrier Sense Multiple Access (CSMA) is a preferable choice for Medium Access Control (MAC) protocols. However, it also increases the overall delay. In this paper, a Priority MAC protocol for Multi-Event industrial wireless sensor networks (PMME) is proposed. In PMME, use of different ${p}$ values/sequences is proposed to enable multi-priority operation, which can be optimized to suit different operational classes within industrial applications including emergency, regulatory control, supervisory control, open-loop control, alerting and monitoring systems. In this work, novel mathematical model as well as simulations are presented to validate the accuracy and performance of the proposed protocol. Mathematical analysis shows that the proposed PMME can prioritize data packets effectively while ensuring ultra-reliable and low latency communications for high priority nodes. Simulations in Castalia verify that PMME with different ${p}$ values/sequences notably reduces packet delay for all four priority classes. The PMME also returns a high packet success rate compared to other two well-known priority enabled MAC protocols, QoS aware energy-efficient (QAEE) and multi-priority based QoS (MPQ), in multi-event industrial wireless sensor networks.

多事件工业无线传感器网络的p持续载波侦听多路访问时延和可靠性分析

在工业环境中,各种事件可能同时发生,并且可能需要基于不同优先级提供不同的服务质量 (QoS)。为了减少冲突的机会并提高多事件发生的效率,载波侦听多路访问 (CSMA) 是媒体访问控制 (MAC) 协议的首选。然而,它也增加了整体延迟。在本文中,提出了一种用于多事件工业无线传感器网络 (PMME) 的优先 MAC 协议。在 PMME 中,建议使用不同的 ${p}$ 值/序列来实现多优先级操作,可以对其进行优化以适应工业应用中的不同操作类别,包括紧急情况、监管控制、监督控制、开环控制、警报和监控系统。在这项工作中,提出了新颖的数学模型和模拟来验证所提出协议的准确性和性能。数学分析表明,所提出的 PMME 可以有效地对数据包进行优先级排序,同时确保高优先级节点的超可靠和低延迟通信。Castalia 中的模拟验证了具有不同 ${p}$ 值/序列的 PMME 显着降低了所有四个优先级类别的数据包延迟。在多事件工业无线传感器网络中,与其他两个众所周知的启用优先级的 MAC 协议、QoS 感知节能 (QAEE) 和基于多优先级的 QoS (MPQ) 相比,PMME 还返回高数据包成功率。数学分析表明,所提出的 PMME 可以有效地对数据包进行优先级排序,同时确保高优先级节点的超可靠和低延迟通信。Castalia 中的模拟验证了具有不同 ${p}$ 值/序列的 PMME 显着降低了所有四个优先级类别的数据包延迟。在多事件工业无线传感器网络中,与其他两个众所周知的启用优先级的 MAC 协议、QoS 感知节能 (QAEE) 和基于多优先级的 QoS (MPQ) 相比,PMME 还返回高数据包成功率。数学分析表明,所提出的 PMME 可以有效地对数据包进行优先级排序,同时确保高优先级节点的超可靠和低延迟通信。Castalia 中的模拟验证了具有不同 ${p}$ 值/序列的 PMME 显着降低了所有四个优先级类别的数据包延迟。在多事件工业无线传感器网络中,与其他两个众所周知的启用优先级的 MAC 协议、QoS 感知节能 (QAEE) 和基于多优先级的 QoS (MPQ) 相比,PMME 还返回高数据包成功率。
