面向WIA-PA工业无线传感器网络的确定性调度算法
Deterministic Scheduling Algorithms for WIA-PA Industrial Wireless Sensor Networks
摘要
Abstract
Wireless Networks for Industrial Automation Process Automation (WIA-PA) is China's national standard for industrial wireless sensor networks.Deterministic scheduling is one of the key technologies for WIA-PA networks.However,current deterministic scheduling algorithms mainly focus on the common wireless sensor networks or WirelessHART and ISA100.11 a networks,and they are not optimized for WIA-PA networks.Therefore,an optimal backtracking scheduling algorithm is proposed and achieves the optimal schedulable ratio for WIA-PA networks.And based on this,another deterministic scheduling algorithm called Least Slack First on Time Division Multiple Access (LSF-TDMA) is further presented.Simulation results demonstrate that LSF-TDMA algorithm can meet the deterministic demand of end-to-end data transmissions in WIA-PA networks.It obtains a near-optimal schedulable ratio while effectively reducing the algorithm complexity.关键词
