Mobile nodes in wireless LANs connect themselves to the Internet via their associated access points (AP). Although more and more APs are being deployed, nodes tend to gather around some common hotspots, contending for few APs and leaving other APs idle. The traffic unbalance affects both per-node throughput and network throughput. In this paper, we aim to(More)
In emerging wireless communication environments, a variety of wireless systems will coexist using a variety of applications. On the other hand, concern is increasing that the growing use of wireless systems will exhaust finite radio resources. Cognitive radio, which aims to optimize the utilization efficiency of radio resources by combining multiple(More)
