A Dynamic Scheme for Multimedia Support in IEEE802.11 Wireless Network

摘要：

With the development of wireless network,a solution is urgently expected to meet the higher-quality QoS demands of multimedia traffics especially when the network is heavily loaded. This paper presents a new scheme of MAC protocol of wireless network. optimizing the services of the system in time of load change input via adjustment of the times of the access gated services.The scheme does not modify the current protocol infrastructure or add any overheads.The theoretical model is established .with Markov chain and probability generating function. Mathematical analysis is made on the mean queue length and the mean cyclic time of the common queue and the key station. It turns out that the findings from theoretical analysis correspond well with those from simulated experiments and strengthen the flexibility and fairness of multimedia transmissions in wireless system.
