Distributed sensor network

Abstract : The Distributed Sensor Networks (DSN) program is aimed at developing and extending target surveillance and tracking technology in systems that employ multiple spatially distributed sensors and processing resources. Such a system would be made up of sensors, data bases, and processors distributed throughout an area and interconnected by an appropriate digital data communication system. Surveillance and tracking of low-flying aircraft has been selected to develop and evaluate DSN concepts in the light of a specific system problem. A DSN test bed that will make use of multiple small acoustic arrays as sensors for low- flying aircraft surveillance is being developed and will be used to test and demonstrate DSN techniques and technology. This Semiannual Technical Summary (SATS) reports results for the period 1 October 1982 though 31 March 1983. Initial validation tests of a three-node message-based distributed acoustic surveillance system were conducted during this reporting period. The system consisted of three test-bed nodes interconnected and controlled by a separate experiment control and communication (ECC) computer. In addition to providing message based internodal communications, the ECC also serves as a system user interface. Improvements needed to support detailed distributed system experiments were identified and have been partially implemented.
