A matching-based strategy for AP selection in sustainable heterogeneous wireless networks

This paper considers a problem of user and access point associations in heterogeneous wireless networks consisting of multiple radio access technologies. We propose a strategy for optimizing the problem that aims at maximizing the total minimal utility of users in the longer term. The minimal utilities can be obtained from bare essentials of the quality of experience and defined by considering different requirements of each user. In order to analyze characteristics of the proposed selection strategy, we conduct simulations comparing it with other selection mechanisms under criteria such as minimal utility, sustainability, fairness, and load balancing.
