摘要
为了有效地控制对无线网资源的使用,针对自适应的多媒体应用带宽可以动态调整的特点以及价格对用户行为的影响,提出一种与价格机制相结合的自适应的接纳控制算法,该算法适合于无线网中具有多服务类、多优先级服务的情况,并根据网络当前状况动态地调整价格以缓解拥塞问题。该价格机制力求在有效性和易用性之间做出权衡。最后与未结合价格机制的自适应接纳控制算法进行性能对比表明,将价格机制与接纳控制结合起来,可以很大程度上改善无线网的性能。
In order to efficiently and effectively control the use of wireless network resources, in this paper, according to the characteristic of adaptive multimedia applications in which bandwidths can be adjusted dynamically, and the influence of pricing on the users＇ behavior, an adaptive admission control algorithm integrated with pricing is proposed. The algorithm, in with the price is adjusted dynamically based on the current network conditions, is fit for the multi-priorilies services. Attempt is tried to make best balance between the efficiency and simplicity for the pricing scheme. Comparison of the performance of the proposed approach is made with the corresponding results of conventional systems where pricing is not taken into consideration in CAC process. The performance results verify the considerable improvement achieved by the integration of pricing with CAC in wireless networks.
