 | We consider the problem of sensor node localization in a randomly deployed sensor network, using a mobile access point (AP). The mobile AP can be used to localize many sensors simultaneously in a broadcast mode, without a preestablished sensor network. We consider a multi-modal approach, combining radio and acoustics. The radio broadcasts timing, location information, and acoustic signal parameters. The acoustic emission may be used at the sensor to measure ... |

|
 | (U) THIS PAPER PRESENTS ISSUES AND ALGORITHMS FOR THE PROBLEM OF MULTIPLE SOURCE TRACKING WITH A NETWORK OF AEROACOUSTIC SENSORS IN A STUDY OF DATA FUSION FROM SENSORS THAT ARE WIDELY SEPARATED, GIVING PARTICULAR ATTENTION TO THE IMPORTANT ISSUES OF LIMITED COMMUNICATION BANDWIDTH BETWEEN SENSOR NODES, SIGNAL BANDWIDTH, AND NOISE. THE PAPER COMPARES THE TRACKING PERFORMANCE OF VARIOUS SCHEMES, INCLUDING JOINT (COHERENT) PROCESSING OF ALL SENSOR DATA, AS WELL AS ... |

|
| (U) THIS PAPER PRESENTS PERFORMANCE BOUNDS (ZIV-ZAKAI) FOR THE RESULTS OBTAINED FROM MULTIPLE SENSOR ARRAYS DISTRIBUTED OVER A REGION TO PROVIDE THE MEANS FOR ACCURATE LOCALIZATION OF THE POSITION OF A SOURCE, AND THE DEVELOPMENT OF A NARROWBAND SUBSPACE ALGORITHM FOR SOURCE LOCALIZATION WITH DISTRIBUTED ARRAYS AND PARTIALLY COHERENT SIGNALS. THE PAPER CLAIMS TO SHOW THROUGH ANALYSIS, SIMULATION, AND PROCESSING OF MEASURED DATA THAT THE PERFORMANCE OF ALGORITHMS IS LIMITED ... |

|
| (U) THIS PAPER PRESENTS PERFOMANCE ANALYSIS FOR SOURCE LOCALIZATION WHEN WIDEBAND AEROACOUSTIC SIGNALS ARE MEASURED AT MULTIPLE DISTRIBUTED SENSOR ARRAYS. THE ACOUSTIC WAVEFRONTS ARE MODELED WITH PERFECT SPATIAL COHERENCE OVER INDIVIDUAL ARRAYS AND WITH FREQUENCY-SELECTIVE COHERENCE BETWEEN DISTINCT ARRAYS, THUS ALLOWING FOR RANDOM FLUCTUATIONS DUE TO THE PROPAGATION MEDIUM WHEN THE ARRAYS ARE WIDELY SPERATED. THE SIGNALS RECEIVED BY THE SENSORS ARE MODELED AS WIDEBAND GAUSSIAN RANDOM PROCESSES, AND THE ... |
