Research on Middleware in Ubiquitious Sensor Network Envionment
Marie Kim, Jun Wook Lee, Hoy Chan Bang · Advanced materials research · 2012
IT infrastructure is evolving in a way to use physical information for providing context-aware services to the users and if necessary, to put some actions on the physical world for reacting appropriately based on perception on the physical world. Ubiquitous sensor network (USN) environment consists of various types of sensors and actuators to perceive and communicate with physical world. USN middleware is the system which collects physical information from various sensors and controls physical world with heterogeneous actuators on behalf of USN services. ETRI has been researching and developing USN middleware and this paper intends to introduce the results and the ongoing project.
