Balancing Load of APs by Concurrent Association of Every Wireless Node with Many APs

In this paper we propose a novel method for associating Wireless Mobile Nodes (WMNs) to Access Points (APs) in busy wireless access networks. The proposed method associates each WMN with multiple APs for mitigating the load balancing problem in hot-spots. The method assumes that a concurrent multipath transport control protocol such as cmpTCP is used at the end-points. The connections are established and maintained with the help of functionalities of emerging IEEE 802.21 standard. An analytical model for the proposed system has been developed. Numerical evaluation of the closed form solution of the proposed model shows that the proposed model will out-perform any other WMN-AP association method if the all WMNs are within the communication range of APs. The proposed system keeps the AP utilization same but reduces expected service queue length of APs, and reduces expected waiting time for the WMNs.
