Resumo
This work revises existing solutions for a problem of target localization in wireless sensor
networks (WSNs), utilizing integrated measurements, namely received signal strength (RSS) and
angle of arrival (AoA). The problem of RSS/AoA-based target localization became very popular
in the research community recently, owing to its great applicability potential and relatively low
implementation cost. Therefore, here, a comprehensive study of the state-of-the-art (SoA) solutions
and their detailed analysis is presented. The beginning of this work starts by considering the SoA
approaches based on convex relaxation techniques (more computationally complex in general), and it
goes through other (less computationally complex) approaches, as well, such as the ones based on the
generalized trust region sub-problems framework and linear least squares. Furthermore, a detailed
analysis of the computational complexity of each solution is reviewed. Furthermore, an extensive set
of simulation results is presented. Finally, the main conclusions are summarized, and a set of future
aspects and trends that might be interesting for future research in this area is identified.
