US-based security company Lockheed Martin has launched a new wireless sensor network system called the Self-Powered Ad-hoc Network (SPAN) which consists of ground sensors. The sensors are small and can be easily camouflaged according to the surroundings thus enabling continuous surveillance of the secured area.
Each sensor node of the system has a built-in subsystem to harvest energy from surrounding sources thus enabling the sensor to recharge itself. This feature makes the system very cost-effective and eliminates the need for replacing the sensors manually.
For any sensor to work efficiently and serve its purpose its battery life is very important. The sensor nodes can be positioned by using a touch screen interface. Information from the network of sensors is processed within the secured area through algorithms. The network of sensors can also give an indication to the camera or an unmanned aerial vehicle to further survey the area of concern. Since the sensors can be camouflaged easily it makes it difficult for detection and reduces the chances of being tampered with. This in turn provides consistent surveillance and protection.
Particular structures that can make use of the SPAN are bridges, pipelines, aircrafts and other environments where structures have to be monitored. Lockheed Martin has around 126,000 global employees who are focused on the design, development, manufacturing and selling of the company’s advanced technology, services and products.
