Abstract

Conventional context aware services have been built in an ad-hoc manner, making it difficult to build new applications or evolve existing ones. In this paper, we show a sensor proxy based service coordination framework named CASTANET. A CASTANET server serves as a protocol conversion gateway in the network so that different resources in heterogeneous networks can be easily coordinated based on the REST architectural style (Fielding and Taylor, 2002). Different from existing middleware-based approaches, CASTANET framework aims at coarse-grained service coordination that is compatible with existing Web based applications.
