As computing technology moves towards pervasive computing, many applications are beginning to make use of context information to adapt to and respond appropriately to their environments. Such a trend necessitates efficient search for context information in wide-area networks. In this paper, we propose a semantic P2P context lookup system. Peers are grouped(More)
Context information has emerged as an important resource to enable autonomy and flexibility of applications. The widespread use of context data necessitates efficient search services in widearea networks. Centralized context search engines exist, but they suffer from single point of failure and single processing bottleneck problems. In this paper, we(More)
