from Part III - Fairness and cooperation stimulation
Published online by Cambridge University Press: 28 April 2011
Mobile phones are among the most popular consumer devices; the recent developments of 3G networks and smart phones enable users to watch video programs by subscribing to data plans from service providers. Because of the ubiquity of mobile phones and phone-to-phone communication technologies, subscribers can redistribute the video content to nonsubscribers. Such a redistribution mechanism is a potential competitor for the service provider and is very difficult to trace, given users' high mobility. The service provider must set a reasonable price for the data plan to prevent such unauthorized redistribution behavior and to protect the provider's own profit. In this chapter, we analyze the optimal price setting for the service provider by investigating the equilibrium between the subscribers and the secondary buyers in the content redistribution network. We model the behavior between the subscribers and the secondary buyers as a noncooperative game and find the optimal price and quantity for both groups of users. Such an analysis can help the service provider preserve the profit under the threat of the redistribution networks and can improve the quality of service for end users.
