What is Sensor Web System

In this chapter, the authors present different sensor portal architectures for pervasive environments. Each of the portal architecture has been designed for a specific set of applications. Some architectures present users’ data on the sensor web or over the Internet and make them accessible for different applications, such as building maps, developing car management systems, and providing different entertaining services. Other architectures present the data in a meaningful way so that the context of the data is addressed and access to the real-time information is provided. In this chapter, the authors discuss not only these portal architectures with their deployment scenarios, but also highlight some related issues and provide future promising directions accordingly.
