Distributed Estimation in Distributed Sensor Networks

Abstract: A distributed sensor network (DSN) provides a very rich scenario for the study of distributed estimation problems. Two important distributed estimation problems in DSN which hitherto have not received much attention in the literature are considered in this paper. The first problem is distributed multi-target tracking and classification. A distributed multi-target tracker and classifier, obtained by decomposing a centralized Generalized Tracker/Classifier is presented. The second problem is related to the network structure of a DSN. By considering a static estimation problem, we illustrate the main issues and present some results.

Generation of the Mode Select Sensor Network Coverage Map.

Abstract: : This paper describes the technique of designing the network management coverage map files necessary to coordinate a network of Mode S sensors. First, the concept of the Mode S network is defined, and the functions of Network Management are briefly described, as they relate to the coverage map. Then, the rationale for the coverage map is given together with definitions of the map structure and the information required in the file. Implementation of these definitions is illustrated in terms of a specific example: a network of four Mode S sensors in the Washington, D.C. area. As configured, each of the sensors provides service to only one of four ATC facilities (three TRACONs and one ARTCC). The resulting map generation process illustrates not only the general principles but also the significant effects of the ATC control area geometry. Finally, the procedure required for automated map generation is defined. This procedure assumes the use of an interactive computer display terminal and is applicable to any sensor network and ATC facility configuration. (Author)
