Multi-Target Localization Based on Unidentified Multiple RSS/AOA Measurements in Wireless Sensor Networks

Abstract: All existing hybrid target localization algorithms using received signal strength (RSS) and angle of arrival (AOA) measurements in wireless sensor networks, to the best of our knowledge, assume a single target such that even in the presence of multiple targets, the target localization problem is translated to multiple single-target localization problems by assuming that multiple measurements in a node are identified with their originated targets. Herein, we first consider the problem of multi-target localizati… Show more

“…Typically, the specifics of the RF signal environment are not identified. Thus, the most efficient model that is taken into account all the considerations [11], [12]. Various propagation models have been used and classified into: firstly, the empirical models, which depend on the measurement for a specific region, such as log-distance, Okumura models, and Hata models.…”

“…Node localization algorithms in WSNs are mainly divided into range-based localization algorithm and range-free localization algorithm [15]. The range-based localization algorithm mainly included RSSI [16], TOA [17], TDOA [18], and angle of arrival (AOA) [19]. The range-free localization algorithm included centroid [20], weighted centroid, DV-Hop, amorphous [21], and APIT localization algorithm [22].…”

“…In a passive sensor network, there may be multiple signal sources, and before accurate localization, one should first correctly associate observations regarding the same sources [9]. The multi-dimension assignment model is a classical method for data association in passive sensor networks [10][11][12], but it needs the locations of signal sources, which is unavailable before correct data association.…”
