Abstract

In peer-to-peer (P2P) overlay networks, multimedia contents are in nature distributed to peers by downloading and caching. Here, a source peer transmits a multimedia content to a receiver peer. A peer is realized in a process of a fixed mobile computer. A peer on a mobile computer moves in the network. Thus, not only receiver peers but also source peers might move in the network. In this paper, we would like to discuss how source peers deliver multimedia contents to receiver peers in a streaming model so that enough quality of service (QoS) is supported in change of QoS of network and peer, possibly according to the movements of the peers. If a current source peer is expected to support lower QoS than required, another source peer takes over the source peer and starts sending packets of the content. The receiver peer is required to receive packets of the content with enough QoS, e.g. no packet loss even if the source peer is being switched with a new source peer.
