关于低延时性能于无线网络中的研究

In accordance with the thought of dividing serving class, we optimize the mechanism of the 802.11 MAC layer, make simulation on NS2, analyze the function compared with the one before optimization in view of the real-time service, and finally testify the result of the optimization. A solution for supporting low-delay services for the MAC layer is proposed. And it can realize the dividing of the real-time and non-real-time services, and then we build a new MAC mechanism serving for different service class by amending the source code of NS2.
