Scheduling Algorithm of Great Tolerance Wireless Communication Delay for Wireless Network Control System

A majority of existing scheduling models of network control system are designed without considering the characteristic of wireless technology. They face serious degradations in wireless industrial applications. This paper proposed scheduling algorithm of great tolerance wireless communication delay (GTD). This algorithm resolves real-time problem of cycle communication task in wireless network control system (WNCS), and eases overtime phenomenon of cycle communication task caused by wireless network delay partly. Finally, we evaluate the performance of the proposed GTD for the WNCS. Simulation results show that it is more effective than traditional scheduling algorithms in the WNCS applications.
