基于Wireless HART的工业无线网络资源分配公平性算法

The fairness algorithm of industrial wireless network resource allocation based on wireless HART

在资源受限的工业环境中,由于通信资源分配的不合理,工业无线网络中仍然存在资源利用率不高甚至是资源浪费的问题.有鉴于此,针对基于时分多址的Wireless HART网络,提出一种基于整体公平的资源分配优化算法.算法考虑网络吞吐量和通信资源分配公平性之间的均衡,通过对不同网络协议层通信资源的联合优化分配,在确保系统吞吐量的同时,最大化网络通信资源分配公平性,提高资源受限的工业无线网络的资源利用率.仿真结果显示,公平性分配策略在保证吞吐量的同时还可以提高资源分配公平性,具有很高的可行性.

In the resource-constrained industrial environment,due to the unreasonable allocation of communication resources,there is still a problem of low resource utilization or even resource waste in industrial wireless networks.Therefore,an optimal resource allocation algorithm based on global equity is proposed for Wireless HART networks based on TDMA.The algorithm considers the balance between network throughput and the fairness of communication resource allocation.By optimizing the joint allocation of communication resources of different network protocol layers,the algorithm maximizes the fairness of network communication resource allocation while ensuring system throughput,and improves the resource utilization rate of resource-constrained industrial wireless networks.The simulation results show that the fairness allocation strategy can not only guarantee the throughput but also improve the fairness of resource allocation,which is highly feasible.
