Due to bandwidth constraints between the sens ors and a fusion center (FC)\, it was envisioned that condensed sensor dat a\, rathe than the raw data\, would be sent to the FC. Based on a mathemat ical and statistical framework and optimality criterion of Bayes cost or N eman-Pearson lemma\, such investigations revealed some surprising results like the optimality of dissimilar sensor processing schemes even when sens ors observe independent and identical sensor data. Earlier framework assum es bandwidth limitations\, but nevertheless assumed error free links betwe en the sensors and FC. With the increased use of wireless sensor networks in a wide range of applications\, where sensors have only a limited power and processing capability\, it becomes necessary to assume power and bandw idth constraints\, thereby resulting in non-error-free communications chan nels. In this talk\, we will present some key earlier results and then dis cuss some new developments in decentralized detection involving wireless s ensor networks.\n\nProf. RAMANARAYANAN VISWANATHAN\n\nBiography\n\nReceive d the B.E.
