Recently, many researchers interested in core technology related to USN(Ubiqutious Sensor Network) with emerging Ubiqutious computing era. Especially, researched about various wireless telecommunication technologies such as ZigBee, Bluetooth, WLAN, CDMA, and various sensor nodes such as nano, Mote, and NeurFon are progressed in universities and research institutes of the world. In this paper, an advanced algorithm is proposed by analyzing problems of circumstance recognition and conventional real-time QoS of USN middleware technology. Finally, the performance of the proposed USN middleware is demonstrated through simulation.
