As a convenient and low-cost wireless technology, WiFi has been widely used for indoor localization, usually based on the Received Signal Strength (RSS) and the fingerprinting algorithms. However, heterogeneous wireless devices measure RSS differently, and impact the localization accuracy significantly. In this paper, we will present a novel linear coding scheme performed on the RSS measurements and...
Energy-based multisource localization is an important research problem in wireless sensor networks (WSNs). Existing algorithms for this problem, such as multiresolution (MR) search and exhaustive search methods, are of either high computational complexity or low estimation accuracy. In this paper, an efficient expectation-maximization (EM) algorithm for maximum-likelihood (ML) estimation is presented...
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...
