| 摘 要： | 区分服务(DiffServ)作为一种服务质量(QoS)的范例已经在有线网络中发挥了很好的作用,通过研究DiffServ在无线环境下的应用,在保证区分服务原有组件的功能不变的前提下,引入移动节点,构建无线网络,并在此环境下用NS-2对其仿真。从仿真结果来看,D iffServ应用于无线网络可以根据用户的不同需求向其提供不同级别的服务,既提高了分组数据传输性能,又有效利用了网络资源。

| Abstract: | As a scheme of QoS,DiffServ plays an important role in wired network,this paper mainly focuses on the application of DiffServ in the wireless environment.Under the premise of keeping the function of DiffServ module unchanged,some mobile nodes to build a wireless network are imported,and a simulation using NS-2 on this topological structure is presented.The result of simulation shows that,in the wireless environment,DiffServ can provide different rank services according to the requirment of users.As a result,DifftServ can both improve the quality of service and efficiently utilize the network resource. |
