Game-Theoretic Pricing for Video Streaming in Mobile Networks(2012)


Game-Theoretic Pricing for Video Streaming in Mobile Networks(2012)


ABSTRACT
Mobile phones are among the most popular consumer devices, and the recent developments of 3G networks and smart phones enable users to watch video programs by subscribing data plans from service providers. Due to the ubiquity of mobile phones and phone-to-phone communication technologies, data-plan subscribers can redistribute the video content to nonsubscribers. Such a redistribution mechanism is a potential competitor for the mobile service provider and is very difficult to trace given users’ high mobility. The service provider has to set a reasonable price for the data plan to prevent such unauthorized redistribution behavior to protect or maximize his/her own profit. In this paper, 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. Based on the behavior of users in the redistribution network, we investigate the evolutionarily stable ratio of mobile users who decide to subscribe to the data plan. Such an analysis can help the service provider preserve his/her profit under the threat of the redistribution networks and can improve the quality of service for end users.
EXISTING SYSTEM
In existing system mobile phones are among the most popular consumer devices, and the recent developments of 3G networks and smart phones enable users to watch video programs by subscribing data plans from service providers. Due to the ubiquity of mobile phones and phone-to-phone communication technologies, data-plan subscribers can redistribute the video content to nonsubscribers. Such a redistribution mechanism is a potential competitor for the mobile service provider and is very difficult to trace given users’ high mobility. The service provider has to set a reasonable price for the data plan to prevent such unauthorized redistribution behavior to protect or maximize his/her own profit.
PROPOSED SYSTEM
In proposed system 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. Based on the behavior of users in the redistribution network, we investigate the evolutionarily stable ratio of mobile users who decide to subscribe to the data plan. Such an analysis can help the service provider preserve his/her profit under the threat of the redistribution networks and can improve the quality of service for end users.
Advantages
1.      Easily identified the secondary buyers.
2.      Only subscriber only watches the video from service provider.
3.      Only authorized user only downloads the videos.
Disadvantages
1.      More than user downloads same video in same time process will be slow.
2.      Some time make a signal problem in unconditional weather.
MODULE DESCRIPTION:
1.      Game theory
2.      Subscriber Module
3.      Secondary Buyers
4.      Admin module
Game theory
Game theory is the formal study of conflict and cooperation. Game theoretic concepts apply whenever the actions of several agents are interdependent. These agents may be individuals, groups, firms, or any combination of these. The concepts of game theory provide a language to formulate structure, analyze, and understand strategic scenarios.
Subscriber Module
In this module subscriber choose video and download the video from service providers. Subscribers pay the amount to service provider. Service provider provides that video key to subscriber. So subscribers watch the video using video key. Also subscriber, redistribute the video to another user such as using blue tooth or Wi-Fi technologies.
Secondary Buyers
In this module secondary buyers easily getting the video from subscriber using Wi-Fi or blue tooth technologies. Secondary buyers don’t pay the amount to service provider. And same time secondary buyers don’t have a video key. But same time secondary buyer does not possible to watch that video.
Admin module
In this module admin upload the video to database. Also view the subscriber details and user details. Admin find the redistribute details. Also who send the video and receive the video.
