Eksperimenter med trådløst sensornettverk for perimetersikring og akseovervåkning

The purpose of the Concept, Development & Experimentation (CDE) project «EP1257 Trådløst sensornettverk (Wireless Sensor Network)» has been to study the operational effect of a Wireless Sensor Network in a tactical setting. The activity has been conducted alongside with the project «1141 - Situational Awareness Sensor System (SASS)» and has taken advantage of the wireless sensing nodes developed in this project. The wireless sensor system used in the experiments consisted of 50 nodes equipped with Infrared sensor, an acoustic sensor and doppler radar. In addition to this system, a commercial system, Flexnet developed by Exensor, was used. The wireless sensor systems were used in two scenarios: Perimeter surveillance and road surveillance. The results from the experiments show that the SASS-system was very robust and stable considering that the system is on a very early prototypical stage. The operational results show that a wireless sensor network can provide early detection of adversaries, improve the chain of reaction, and provide improved perimeter security. Our experiences conclude that the system is easy to deploy and simple to use. Further, it is reason to believe that electronic sensors can reduce the workload compared to using traditional observation soldiers.
