Design of the middleware for wireless sensor node based on IEEE1451.5

Ubiquitous sensor network (USN) systems require a mutually well combinable sensor middleware while maintaining system independence. These middleware are provided differently according to the system characteristics of each producer. Due to these proprietary APIs, Middleware are not applicable for compatibility between a variety of applications and Hardware platforms. National Institute of Standards and Technology (NIST) has offered IEEE1451 which provides common interface and API to maintain independence and compatibility between a network and a transducer such as an actuator and a sensor. This paper suggests the Simple middleware for the Wireless sensor node using a standard API of IEEE1451.5 This middleware can keep the transducer and network module mutually independent and compatible because it uses IEEE1451.5 API between application and hardware platform. Network Capable Application Processor (NCAP) and Wireless Transducer Interface Module (WTIM) required for the connection of the Ubiquitous is designed with this middleware and a data transmission is checked after understanding an order of a previously suggested simple middleware-mounted wireless connection protocol of WTIM.
