Sensor networks

Especially the advancing technological developments in the domain of micro-electro-mechanical-systems (MEMS) yields in a miniaturization of sensors. These technological evolution enables the construction of sensor nodes consisting of wireless communication device, memory processor, and a battery pack. Such tiny sensors allow the construction of new sensor networks with an previously unknown high network density.

Collections of a large number of heterogeneous intelligent sensors that are spatially distributed over an environment and connected through a communication network are called distributed sensor networks (DNS).

Sensor Web

Sensor Web is a coordinated observation infrastructure composed of a distributed collection of resources that can collectively behave as a single, autonomous, taskable, dynamically adaptive and reconfigurable observing system that provides raw and processed data, along with associated meta-data, via a set of standards-based service-oriented interfaces. In contrast to sensor networks, the developments of the sensor web focus on an interoperable service oriented architecture.
