The authors are developing a flexible sensor network with numerous potential uses. This paper presents one constructive application of the sensor integration platform and network. The theory of operation is as follows. Multiple sensing/processing nodes are scattered about a 30-­mile radius on land. Each node has the capability to handle up to a few different sensors based on user needs. The nodes operate autonomously while continuously acquiring data and process the information locally. The information deemed relevant to the system operator is uplinked to a base station at optimal intervals. Further data collection takes place at the base station where an operator can take appropriate action. Communication between the base station and nodes is based upon the emerging IEEE 802.16 standard. This enables broadband level information transfer at ranges capable of covering entire metropolitan areas. The application discussed in this paper is a homeland security monitoring system. This system would make use of a variety of nodes to collect data from surveillance cameras at border crossings and high value assets, water contamination sensors, weather sensors, and other sensors the user sees necessary. A technical description of the system architecture, its benefits, and limitations will be included. The utility of the 802.16 standard will also be incorporated in the paper.
