Application of session initiation protocol to networked sensor interfaces

Network of measurement and control is now converging with network of information tightly more and more, which improves the development of network-distributed measurement and control technology. And networked sensors are important unit in networked measurement and control system. This paper applied Session Initiation Protocol (SIP) to networked sensors system aimed for a kind of unified IEEE 1451 NCAP model of networked sensors using SIP as the interface. We analyzed the features of SIP and sensor network interface, presented a frame of networked sensor based on SIP according to IEEE1451 sensor standards, and studied on-line register of networked sensor based on SIP. Devices supported by SIP in distributed control system can communicate easily with IP-based information network, and can also provide conveniently multimedia service. SIP and P2P SIP are worthy of deep research for networked sensor system.
