CAP:: A context-aware peer-to-peer system

Despite various hurdles, as copyright issues and security concerns, peer-to-peer (P2P) networks and systems still grow and gain in popularity, and the research community continues to develop interesting applications of P2P technology, together with new platforms for application development. Because the overall performance of these platforms and applications also depends on the performance of the background routing protocol, new systems are mostly based on distributed hash tables (DHT), which are algorithms that provide efficient mechanisms for resource location. However, DHTs assume the system is uniform in available resources and that every node participating in the DHT is within the same transport domain. A number of earlier works has gone on topology-awareness, as a possibility to improve the system's lookup performance. In this paper, we go. on to a configurable context-aware system and propose CAP, a novel scheme, which promises contextual data retrieval, alleviated message latency, and enhanced lookup time.
