Network selection is a key problem when a user faces multiple available wireless networks. Especially, this problem becomes more complicated when multiple users share multiple wireless networks due to the interaction and competition among users. Most existing works on this multiple networks sharing problem assume that users have the same utility functions, which neglect the fact that users may have...
Nowadays there is a plethora of independent radio access technologies (RATs), each supporting distinct coverage, mobility, data rates, and quality of service (QoS). The cornerstone of all visions on future wireless networks is that there will be a multiaccess network environment, where users will be able to select from various available multiple heterogeneous access networks the most appropriate one...
Measurement studies have shown that uneven and dynamic usage patterns by the primary users of license based wireless communication systems often lead to temporal and spatial spectrum underutilization. This provides an opportunity for secondary users to tap into underutilized frequency bands provided that they are capable of cognitively accessing without colliding or impacting the performance of the...
The network selection problem in next generation heterogeneous wireless networks is one of the key issues to integrate a wide range of radio access technologies. In most previous work, the network selection problem is modeled as a centralized system, without considering the distributed nature of heterogeneous wireless networks. In this paper, we propose a distributed network selection scheme in heterogeneous...
