A Study on WSN System Integration for Real-Time Global Monitoring

Since Wireless Sensor Networks (WSNs) have a lot of potential capability to provide diverse services to human by monitoring things scattered in real world, they are envisioned one of the core enabling technologies for ubiquitous computing. However, existing sensor network systems are designed for observing special zones or regional things by using small-scale, low power, and short range technologies. The seamless system integration in global scale is still in its infancy stage due to the lack of the fundamental integration technologies. In this paper, we present an effective integration avenue of real-time global monitoring system. The proposed technology includes design, integration, and operational strategies of IP-WSN based territorial monitoring system to ensure compatibility and interoperability. We especially offer the standardizations of sensing data formats and their database interfaces, which enable a spontaneous and systematic integration among the legacy WSN systems. The proposed technology would be a fundamental element for the practically deployable global territorial monitoring systems.
