无线回程网中的公平性模型研究

Research of Fairness Model in Wireless Backhaul Networks

在分析无线回程网的三个公平性目标的基础上,提出一种新的带权支流最大最小公平性模型,通过对该模型的非线性规划将其推广到带权支流的一般公平性模型,并给出一般模型的分布式算法,实例仿真分析了几种不同公平性模型下系统的吞吐量和公平性,结果表明该带权支流模型一方面较好的兼顾了吞吐量和公平性,另一方面易于推广且可用分布式算法实现.

Built on three fairness objectives in wireless backhaul networks,a new max-min fairness model with weighted subflow was proposed. A fairness model with weighted subflow was generalized by using nonlinear programming to describe the max-min model,and a distributed algorithm of general model was given. Through simulation of an example,system throughput and fairness was discussed on several different fairness models.Result shows that on one hand the throughput and fairness of proposed model are well taken into account, on the other hand the model can be easily generalized and realized with distributed algorithm.
