Based on wireless sensor network, this paper discussed the methods to estimate acoustic source location with the energy received. Multiple resolution (M-R) and Tabu heuristic algorithms are expounded in details. Then, a new algorithm is proposed to attain the balance between accuracy and calculation complexity. Comparison among the different methods was made according to simulation data and curve...
Multi-source localization is an open and challenging research problem in the energy-based wireless sensor network (WSN) of acoustic sensors. Classic maximum likelihood (ML) algorithm can not work well due to the high computation demand. An expectation maximization (EM) algorithm was proposed in our previous paper to approximate the optimal solution with lower computational complexity. However that...
A new efficient expectation-maximization (EM) algorithm for ML estimation is presented for multiple sources localization using a wireless sensor network (WSN). It uses acoustic signal energy measurements taken at individual sensors to estimate the locations of multiple acoustic sources. Instead of already existent multi-resolution (MR) search of projection solution and existing EM algorithms for ML...
