D4.6 Viability of WSN as ICT overlay for physical security detection

A state of the art review covers the latest trends in Real Time Location Systems, firstly covering the general theory behind it, then delving into the technologies currently employed for indoor location. The different methods are compared in order to determine the most likely optimal choices for the use cases giving initial recommendations. One issue with these systems is battery life expectancy of the wireless sensors and so energy harvesting techniques are examined to eliminate the need for battery replacement or at least extend battery life. For physical security detection and determination, a number of typical sensors used for security purposes are covered. A general high-level specification of the final system is laid out as well.
