Traffic Offloading and Edge-networking Solutions: Theory and Realizations The proliferation of mobile Internet access poses new challenges to wireless service providers as the capacity growth of their networks cannot cope with the rate of increase of mobile wireless traffic. Alternate means are considered to deal with the excessive traffic demand, that exploit the proliferation of wireless networks in unlicensed parts of the spectrum as well as of handheld devices with multiple radio interfaces. We will present a scheme where operators may gain access to WiFi access point networks and negotiate with their owners permission to offload mobile traffic from the cellular network. That scheme is based on a double auction mechanism that allows both the cellular operators and the access point owners that seek the most beneficial arrangements for themselves to reach an agreement for traffic offloading. Additionally, we will discuss user-provided networks where mobile users cooperate to address various network impairments in a bottom-up fashion and improve their Internet access performance and cost. We will first present an incentive mechanism that encourages user participation in such crowd-sourced Internet provisioning schemes. Accordingly, we will analyze the architecture and the performance of a novel system design which supports such edge-networking solutions by leveraging SDN-enhanced mobile devices and cloud services.
