Mobile Data Offloading

With the proliferation of smartphones and tablets, the demand for mobile data has been growing very rapidly. Cisco recently forecasted that the global mobile data traffic would increase by 13- fold between 2012 and 2017. This is pushing the mobile cellular network to its limit, given the relatively slow growth of the cellular network capacity.

On the other hand, the Wi-Fi technology is uniquely positioned to complement the cellular technology, due to its unlicensed nature and the worldwide adoption at home and work. In particular, Wi-Fi networks can help to offload the traffic from over-stressed cellular networks, and reduce cellular operators’ costs and increase users’ service satisfactions. To achieve a seamless integration of cellular and Wi-Fi technologies, however, requires us to have forward-looking policy reforms, effective economic mechanism designs, and innovative technology solutions. This will lead to a paradigm shift in the mobile ecosystem, and will affect the technical and economic decisions of spectrum regulators, cellular and Wi-Fi operators, and mobile users.

In this project, we plan to address the following two key questions: (1) How to provide economic incentives to maximize and fairly share the data offloading benefits in the network? (2) How to optimize data offloading algorithms that best trade off network cost reductions and users’ Quality of Service improvements?
