一种认知网络中的带宽分配方法研究

Research on a Bandwidth Allocation Algorithm in Cognitive Network

认知网络作为一种新型的网络概念和技术,近年来其重要性得到了广泛的认同。在认知网络中,如何根据用户业务需求及带宽资源状况动态进行带宽分配是一个重要的问题。通过对用户权重的估计分析,提出了一种基于权重估计的改进带权Max-Min带宽分配算法,仿真试验证明该算法可改善对用户业务流QoS的整体保障能力。

As a new network concept and technique, the importance of cognitive network has been widely approved in recent years. In cognitive network,it is a crucial subject how to make bandwidth allocation dynamically based on user requirements and available bandwidth resources. Based on analysis of weights of different users,this paper proposes an improved weighted Max-Min bandwidth allocation algorithm. The simulation results show that this algorithm can improve user QoS guarantee capability as a whole.
