: This paper studies an incentive structure for cooperation and its stability in peer-assisted services when there exist multiple content providers, using a coalition game theoretic approach. An intriguing piece of news is that Prof. Sergiu Hart, who authored the key reference of our paper, is one of the plenary speakers at the conference.
