Abstract

In ubiquitous environment, with rapid advances being made in sensor technology, wireless sensor networks (WSNs) have emerged to collect information from real world. For sharing huge amount of sensor data efficiently with divers users, an information dissemination mechanism is very necessary and important component. In this paper, we have proposed the information dissemination architecture, which is implemented using OGSA-DAI and web services based on Info-D standard, and an efficient matching algorithm, CGIM, for u-health care system. The information dissemination system supports scheduling for both time and event driven delivery and EAQ for 1:1 event and n:1 event handling. From CGIM algorithm, matching time is significantly reduced for information dissemination, and the algorithm allows multiple events with ranged predicates, flexible expression for diverse consumers, and efficient matching and partial optimization on pub/sub system.
