Adaptive Usage of Cellular and WiFi Bandwidth: An Optimal Scheduling Formulation
Worldwide, mobile data connectivity is now widespread, but not yet ubiquitous due to coverage limits and cost concerns. Mobile data offloading to Wi-Fi where available - could greatly decrease the usage of cellular data networks. In delay-tolerant applications, one could delay network communication in order to exploit free Wi-Fi connections expected to appear soon. However, Wi-Fi connectivity is limited, and even delay-tolerant applications must meet quality-of-service deadlines. To explore such bandwidth scheduling issues, the authors develop an optimal MILP-based scheduling frame-work.
