Secure sensor data transmission over wireless cellular networks

Significant effort has been recently devoted to research and development of sensor networks for a wide range of possible applications. Here we focus on the design of a biosensor-based, early-warning system that can be used to detect bio-threats and subsequently relay securely this information - through a cellular network and its communications capabilities - to public health surveillance centers for appropriate processing. As such, it represents an alternative approach to population vaccination against specific viruses and biological threats. Issues involving increased security of communications and network dimensioning are addressed in the above context.
