Abstract

We studied the middleware platform, i.e. COSMOS (Common System for Middleware of Sensor Network) as a national project in Korea, for various types of sensor networks such as the Zigbee wireless sensor network (WSN), the CDMA cellular network, RFID and IP-USN based on the 6LowPAN. Our project is focused on sensor network abstraction for various ubiquitous sensor networks (USN). We defined standard interfaces between USN middleware and USN networks as well as application services. We implemented several USN services such as u-Healthcare services to consider important issues such as data quality, realtime data aggregation and performance analysis for accessibility.
