Sensor Web: An Infrastructure for Real-Time Smart Applications

Abstract

Sensor Web, firstly proposed by NASA, is defined as a smart macro instrument for coordinated sensing. It consists of various sensor nodes that not only collect data, but also share data and adjust their behaviors [1-3]. Recently, as the development of Global Earth Observation System of Systems (GEOSS), Smart City and Internet of Things (IoT), tens of millions of heterogeneous sensors, including space-borne, airborne, in-situ and mobile sensors have been deployed in different fields and for various purposes. The earth, the cities have never been thoroughly and dynamically sensed as they are nowadays.
