Efficient Application Integration in IP-Based Sensor Networks
Sensor networks are seen as an important part in emerging office and building energy management system, but the integration of sensor networks with future energy management systems is still an open problem. The authors present an IP-based sensor network system where nodes communicate their information using Web services, allowing direct integration in modern IT systems. Their system uses two mechanisms to provide a good performance and low-power operation: a session-aware power-saving radio protocol and the use of the HTTP Conditional GET mechanism. The authors perform an extensive evaluation of their system and show that Web services are a viable mechanism for use in low-power sensor networks.
