摘要: 提出了模糊路由选择(QoS-FR)模型,定义一组隶属函数来反映对某个度量值的QoS要求,基于模糊规则推理出每条路径的模糊代价.QoS-FR在全网范围内均衡负载,从而减小了链路上拥塞的概率.仿真结果表明,在保证QoS的前提下,该方法可获得更高的链路利用率和更大的吞吐量.

Abstract: In this paper. a fuzzy QoS routing (QoS-FR) model is proposed. A set of membership function is defined to reflect the QoS requirements for each metric. Based on fuzzy rules, a reasonable fuzzy cost is inferred and assigned to each path. The QoS-FR model takes into consideration the balancing of the load in the network to avoid congestion. Simulation results demonstrate that the proposed QoS-FR can produce high throughput and superior link utilization while keeping the QoS guarantee.
