Abstract

In this paper, we propose a new collaborative caching strategy in a push-based broadcast environment where clients construct a peer-to-peer network by connecting with each other. In the proposed strategy, a client takes into account its own access probabilities and information on queries issued by other clients, and caches data items with large benefits of the response time. We confirm that the proposed strategy reduces the average response time by simulation experiments.
