A Middleware for Ubiquitous Sensor Network(USN) exists between sensor software and operating system, and supports maintenance, installation, deployment and software execution. Also, the middleware updates a program and reconfigures software program according to the change of the program. Sensing data type of sensor nodes is often changed in the sensor network. To support change of sensing data type, distributed sensor nodes are collected and the setting of the nodes is updated using external storage. Recent middleware for change updates setting of a sensor node by transmitting the program image. The middleware divides whole program image into several images and trasmits the images using wireless communication, so resource overhead is occurred. Also it is necessary to ensure reliability of divided images. This paper implemented a middleware for updating. In the proposed middleware, attributes for change of sensing data type are stored in EEPROM and updated by transmitting a packet which includes the values of the attributes. For implementation of middleware, this paper defines attributes which can be changed in the sensor node. This paper also proposes a process for updating of attributes values and the structure of the middleware model.
