This brief looks at the viability of deploying such WSNs.Ī Wireless Sensor Network (WSN) is a set of spatially located smart-sensors, to measure one or more parameters ranging from temperature and pressure to capturing video or audio, that feed their data over a common backbone to a repository for storage and analaysis. With the proliferation of sensors on consumer devices, specifically smartphones, there exists an opportunity to leverage the availability of such sensors, at a relatively lower cost than specialized sensor-carrying devices or custom-built sensors, to build a WSN targeted at unearthing and identifying Homeland Security threats. – the current implementations of sensor clouds all involve Wireless Sensor Networks (WSN) in areas as diverse as industrial process monitoring, environmental protection and management, structural monitoring of critical equipment and edifices, and consumer energy consumption management. Although the focus in that brief was on traditional surveillance sensors – video, audio, radar, trace detectors, access control, motion detectors, etc. Briefs last month (November 2011) – The Sensor Cloud and Homeland Security – briefly outlined how Homeland Security agencies can use cloud computing to store and process surveillance sensor data.
