Node localization in wireless sensor networks (WSNs) aims to determine unknown target position given anchors' known positions and available relative pairwise measurements among directly-connected neighboring nodes. From this point of view, WSNs can be divided into two groups based on collaboration between targets: cooperative networks in which the measurements between the targets are also used for...
Estimation of position in the wireless sensor networks is presently taken as prime focus in the field of research and applications. Various innovative location-aware technologies and services are being investigated. Applications area are at present having expansion in both two and three dimensions. In Practical applications, generally only approximate distances are available from sensor to anchors;...
It is a very important and challenging task to localize an audio-source in wireless sensor networks (WSNs). One of efficient methods for audio-source localization is the so-called time difference of arrival (TDOA) based approach. In this paper, we propose a novel localization method based on Generalized Cross Correlation-Genetic Algorithm (GCC-GA). It utilizes GCC method to calculate the TDOA and...
