A Scalable QoS-Aware Service Aggregation Model for Peer-to-Peer Computing Grids

Peer-to-peer (P2P) computing grids consist of peer nodes that communicate directly among themselves through wide-area networks and can act as both clients and servers. These systems have drawn much research attention since they promote Internet-scale resource and service sharing without any administration cost or centralized infrastructure support. However, aggregating different application services into a high-performance distributed application delivery in such systems is challenging due to the presence of dynamic performance information, arbitrary peer arrivals/departures, and systems’ scalability requirement. In this paper, we propose a scalable QoS-aware service aggregation model to address the challenges. The model includes two tiers: (1) on-demand service composition tier, which is responsible for choosing and composing different application services into a service path satisfying the user’s quality requirements; and (2) dynamic peer selection tier, which decides the speciï...
