Abstract

Due to the explosive popularity of peer-topeer (P2P) file-sharing services, there have been remarkable research efforts on the P2P live streaming services. P2P systems are cost-effective and can be easily deployed only by leveraging the participating peer's resources (i.e., upload link bandwidth) to distribute contents. In this paper, we propose Climber, an incentive-based resilient P2P system for live streaming services. Climber encourages each peer to provide more upload link bandwidth to the system, and embodies an incentive mechanism that improves resilience under high churning rate. The structure of Climber is a hybrid of a tree and a mesh, which self-improves and adapts to network churning rate. Simulation results are given to evaluate the performance of the proposed protocol.
