Integrated Sensor Network:
Four fixed and mobile Intelligent Sensing Modules (blue) integrate a network of chemical and biological warfare agent sensors. The sensors are securely monitored and controlled from a remote location by an authorized user.chemical and biological warfare agent sensors. The sensors are securely monitored and controlled from a remote location by an authorized user.Full protection of a facility or urban area often requires use of a variety of detectors to sense different types of weapons, such as chemical, biological, or radiological sensors. However, integrating these diverse detectors into a single system presents two key technical challenges:
Seeing the need, DOE/NNSA engaged Sandia to develop a sensor management architecture (SMA) that allows for rapid integration and deployment of a sensor network. Through deployments in three DOE/NNSA and DoD/DTRA projects, the SMA has demonstrated secure, remote monitoring and control of distributed sensors from one or more locations.
Further, the SMA integrates these command and control capabilities with information received from other aspects of facilities operations. Its software framework enforces data encryption and integrity, and provides configurable "role-based" controls that ensure only approved users can use the system.
The SMA is based on two-Sandia developed technologies:
Intelligent Sensing Modules (ISMs) and the Enterprise Modeling Framework (EMF). In SMA deployments, the ISM hardware provides the wireless communication and data processing capabilities required for sensor communication, and the EMF software provides the data integration architecture and client/server communication capabilities.
