Priority-Based Polling Scheme under Mixed Services Policy of Exhaustive and Three-Times Gated Services
Liyong Bao, Dongfeng Zhao, Yifan Zhao · 2010
Based on the ideas of Priority-based polling transmission with high-efficiency, and self-adaptation to loading, this paper presents a new analysis model of MAC Scheme of wireless communication network, which has made possible the server capable of differentiating the stations of different priority levels under mixed services policy and which has improved the flexibility and adaptability of the system via adjustment of the switch-in service in three time of load change input. The model is established through embedded Markov chain and the probability generating function. Theoretical analysis is made on the mean queue length and the mean cyclic time of the key station and the common stations. The results show that the findings from theoretical analysis correspond well with those from simulated experiments and the scheme guarantee better QoS.
