Wireless Sensor Networks (WSN) is a new technology which allows monitoring natural phenomena in space and time. Originally, wireless sensor networks were used for military applications, but currently they are employed in a variety of civil applications, including surveillance, chemical and biological agent monitoring, security in critical infrastructures, environmental and habitat monitoring, etc. Some of these application areas cover a broad range of objectives. For example, surveillance applications extend from intruders' detection and tracking to in-home monitoring of elderly patients. Environmental applications include land monitoring, recognition of amphibian populations and underwater tsunami and seaquake detection.
