Today’s communication networks are highly complex, carry heterogeneous traffic in diverse environments, and are often owned by multiple profit-making entities. To successfully maintain, optimize, and upgrade such large distributed networks, it is important to design new economic incentive mechanisms as well as develop new technologies. The market deregulation of the telecommunication industry in many countries makes such economic consideration even more urgent, as there are often conflicting goals between the regulators and the commercial operators. We will first illustrate how economics can help us better understand the networking industry reality, predict user behaviors, envision new network services, and provide policy recommendations. Then we will focus on the case study of incentive mechanisms for user-provided networks (UPNs). UPNs is a new communication paradigm, which enables users to improve their communications experiences by exploiting the diverse communication needs and resources of other users. The success of UPNs, however, relies on carefully designed incentive mechanisms that effectively encourage users’ voluntary participations and cooperations. We will introduce a new paradigm of cooperative video streaming based on the concept of UPN, where mobile users crowdsource their Internet connectivities and adaptively choose video downloading sequences and streaming qualities. We will introduce a multi-dimensional auction framework, which effectively incentivizes users to cooperate in a distributed fashion.
