This paper addresses the user association problem in a multi-cell broadcast transmission. We seek minimal total energy consumption by considering both transmission power and operational power cost. We propose a novel distributed solution based on network utility games and using so-called Markovian approximation we design the distributed base station (BS) selection algorithm. Extensive simulatio...

There has been a rapid increase in wireless LAN (WLAN) deployments, users and traffic in the recent years. Most of the current studies in WLAN access patterns have focused on usage statistics and user arrival patterns at access points (APs). However, little work has been done for fine-grained analysis of the structures and trends in long term user AP association patterns. Such detailed study co...

In this paper, we want to improve association rules in order to be used in recommenders. Recommender systems present a method to create the personalized offers. One of the most important types of recommender systems is the collaborative filtering that deals with data mining in user information and offering them the appropriate item. Among the data mining methods, finding frequent item sets and ...
