Facilitating Universal Multimedia Adaptation (UMA) in a Heterogeneous Peer-to-Peer Network

This paper proposes a P2P architecture which uses MPEG-21 as a standard based technique to dynamically adapt resources according to various usage environment attributes such as terminal capabilities and user preferences. In the architecture, a super peer based approach is used to cluster peers, store peer information, perform searches and instruct peers to adapt/send resources. Pull and push-based adaptation methods are introduced to adapt search results and resources in an intelligent manner based on the usage environment attributes. Simulation results show that the proposed architecture reduces download time while increasing resource availabilities and download speed in the network when compared to traditional P2P systems.
