【摘要】 提供服务质量保证是目前无线adhoc网络的研究热点。本文对将区分服务应用于无线adhoc网络进行了阐述,提出了一种应用于无线adhoc网络的区分服务体系结构,最后进行了仿真验证。仿真结果证明,在无线adhoc网络中区分服务可以在资源不够用的情况下,降低对低优先级的业务流的服务,保证对高优先级的业务流的服务,从而使得高优先级的业务流获得较大的吞吐量和较低的延迟。更多还原

【Abstract】 The QoS supporting is a hot researching issue in wireless ad hoc networks. In this paper, we propose a dif- ferentiated service architecture for wireless ad hoc networks. The performance of the proposed architecture is evaluated by simulations. The simulation results show that the proposed architecture can provide better services for higher priori- tized traffic by degrading the qualities of lower prioritized traffic when the network resources are insufficient.更多还原
