An Architecture Concept for Mobile P2P File Sharing Services

Abstract: File-sharing in mobile networks has differing demands to a P2P architecture. Resource access and mediation techniques must follow constraints given in 2.5G/3G networks. Enhancing the eDonkey protocol, we reconcile decentralized operation with traffic control. 1 Requirements for Mobile P2P File Sharing Services P2P systems in mobile environments face multiple challanges: highly varying onlinestate (presence), hierarchical network structure, and limited device capabilities. Network operators desire traffic control while preserving the experience of wired P2P. In order to share resources, P2P applications need to support two fundamental coordination and control functions: a) resource mediation mechanisms, i. e., functions to locate resources or entities, and b) resources control mechanisms, i. e., functions to permit, prioritize, and schedule the access to resources. Pure P2P architecturesare implementing both mechanisms in a fully decentralized manner. Hybrid P2P systems util...
