Abstract:
Network entities cooperating together can improve system
performance of media streaming.
In this paper, we address the ``incentive issue'' of a
cooperative proxy caching system and
how to motivate each proxy to provide cache space to the system.
To encourage proxies
to participate, we propose a ``revenue-rewarding scheme'' to credit
the cooperative proxies according to the resources they
contribute. A game-theoretic model is used to analyze the
interactions among proxies under the revenue-rewarding scheme.
We propose two cooperative game settings that lead to optimal
situations. In particular,
- We propose a distributed incentive framework for peers to
participate in resource contribution for media streaming.
- Proxies are encouraged to cooperate under the revenue-rewarding
scheme.
- Profit and social welfare are maximized in these cooperative
games.
- Cost effective resource allocation is achieved in these
cooperative games.
Large scale simulation is carried out to validate and verify
the merits of our proposed incentive schemes.
