摘要: 为估算网络性能、指导网络规划和设计相应的连接接纳控制算法,研究了无线局域网络的媒体接入控制协议,提出一种无线局域网络的随机服务模型,通过生成函数方法和排队论理论得到了无线局域网络在不同终端数目和不同业务量条件下的性能指标。进一步的,指出对于终端数目较多的无线局域网络,在业务的饱和临界点附近,网络的性能存在突然的恶化,为连接接纳控制算法提供了理论依据。仿真试验验证了模型和结论的合理性。

Abstract: A stochastic service system model based on the media access control protocol is provided for the performance estimation, the layout optimization and the connection admission control algorithm design of the wireless local area network. The network performances for various numbers of stations and various traffic loads are obtained based on the model and queue theory. Furthermore, it is presented that the network performances will deteriorate seriously when the traffic exceeds the saturated threshold in the wireless network with numerous stations and thus it provides theoretically results for the connection admission control algorithm. The model and conclusions are verified by simulations.

Key words: wireless local area network, media access control, connection admission control
