基于超宽带的Ad hoc网络的应用,提出了为多媒体业务提供QoS支持的自适应的资源分配方案。方案考虑了超宽带和Ad hoc网络的特性,同时也考虑了QoS的要求。提出的资源分配方案采取了业务区分和资源预留的方法,为链路分配网络资源(速率、功率)。根据吞吐量,丢包率和时延,对提出的方案做了详尽的性能评估,仿真结果证明了提出的方案的优越性。
Based on the application of UWB Ad hoc networks, an adaptive resource allocation scheme is proposed to provide QoS support for multimedia services. The scheme considers the characteristics of UWB and Ad hoc networks, and also considers the requirements of QoS. The proposed resource allocation scheme adopts the method of service differentiation and resource reservation to allocate network resources (rate, power) for the link. According to the throughput, packet loss rate and delay, the proposed scheme made a detailed performance evaluation, the simulation results prove the superiority of the proposed scheme.
