In the existing works on distributed detection in sensor networks, local sensor nodes either quantize the observation or directly scale the analog observation and then transmit the processed information independently over wireless channels to a fusion center. In this paper, we exploit the advantages of both of these two approaches by constructing an equivalent Sigma-Delta ADC across space over wireless sensor networks. Sensors are arranged in a mixing of parallel and serial topologies, enabling… CONTINUE READING
