In dynamic streaming, a user can dynamically choose from different versions of the same video. In P2P dynamic streaming, there is one P2P swarm for each version, and within a swarm, peers can share video chunks with each other, thereby reducing the server's bandwidth cost. Due to economy of scale, cooperation among peers can also reduce the per-peer content price. In this paper, we use cooperative game theory to dynamically assign each peer to a version. To maximally incentivize peer

With this approach, each peer is assigned to a swarm that is commensurate with its upload contribution and the price it is willing to pay. We also develop and simulate a distributed dynamic P2P streaming algorithm, consisting of chunk scheduling, token-based accounting, and video version switching, to dynamically adjust each peer's video version based on the collaborative behaviors of all peers.
