Acoustic source localization is one of the interesting applications of sensor networks. Localization algorithms that use acoustic signal energy measurements at individual sensor nodes are proposed. The maximum likelihood (ML) algorithm is known as an algorithm for source localization. The ML algorithm has high accuracy to estimate source location, however the calculation amount of the ML algorithm is large. The expectation- maximization (EM) algorithm is proposed to realize the ML algorithm… CONTINUE READING
