Achieving Fairness and Efficiency for Association Control in the Heterogeneous Wireless Networks

摘要：

Jiancheng QIN@School of Computer Science Beijing University of Posts and Telecommunications Beijing, China In the heterogeneous wireless network environment, uneven traffic distribution among different wireless access networks results in the distinction of user network resource. A load balancing scheme is proposed to balance load of diverse access networks, lower unfairness of user bandwidth and improve efficiency of heterogeneous wireless networks (HWNs) resource by association control mechanism. The optimization goal of association control is to achieve user max-min fairness bandwidth. The fairness bandwidth allocation in HWNs is NP-hard problem so an approximation algorithm of polynomial-time is presented to achieve suboptimal result Final simulation demonstrates the presented algorithms performance in user bandwidth fairness and whole system efficiency.
