Adaptive Communications Links for Physical Security Systems

Compromise of security networks is easiest through the communication links. Wired links between sensors and their controls require skilled preplanning and installation. They are expensive to maintain, especially in the connections to central security monitors and command centers. We propose to use a radio based communication system to replace the hardwire/fiberoptic links. This sysem is packet radio based and uses an adaptive method of network and communication optimization. The key feature is that each reporting node in the system is a transceiver that acts as independent data transfer switch. Each transceiver will automatically adapt to network fault problems, data errors, and change data routing patterns without human intervention. Radio packet transmnissions will permit encryption and the use of anti-jamming techniques. AES will develop the software protocols and hardware needed to build a demonstration system which will automatically reconfigure and optimize the security network to pass data between each node and a central control. AES has extensive overseas and domestic experience in designing and installing radio based security systems. The military and commerical viability of this concept are manifest in ease of deploynment, simplified skill level required for installation, multiple anti-jamming techniques, and elimination of repeaters.
