A Scheduling Strategy Suitable for Industrial Ethernet and Mine WSN Scheduling System
Aiming at the actual requirement of the System of industrial Ethernet Connectivity of wireless sensor networks in underground coal mine, a dynamic priority scheduling algorithm which is applied in the interconnected gateway is presented. The algorithm can avoid the occurrence of the congestion in the interconnected system. Simulation results show that packet loss rate is controlled within 7 to 15%, service response time is controlled within 2.8~7s and average queue length is stable when the interconnected system is three times than the maximum load. However, when the load of the interconnected system has returned to normal, the gateway enters the steady state that packet loss rate is zero only after 6s.
