Rethinking offloading WiFi access point deployment from user perspective
Eyuphan Bulut, Boleslaw Karol Szymanski · 2016
WiFi offloading has been exploited as a quick and viable solution to decrease the burden on cellular networks. In this paper, we study the problem of deploying new WiFi access points (AP) in a city-wide area for offloading purposes. Different than previous work which look at the problem only from operator's perspective and targets the maximization of offloaded traffic volume, we approach the problem by integrating the user perspective as well. We propose a new AP deployment scheme that aims to increase average individual user satisfaction while still achieving high offloaded total data traffic volume from all users. As the simulation results demonstrate, the proposed approach can achieve more user level satisfaction compared to other algorithms that only target offloaded traffic maximization while keeping operator's benefit from offloading close to others.
