Special Issue Information

Dear Colleagues,

Local positioning systems (LPS) have attracted a large amount of research interest over the last few years. Their use in highly demanded accuracy tasks allows the optimal performance of technological systems in harsh environments in which global navigation satellite systems cannot provide a stable accurate target location. Consequently, the deployment of alternative localization systems based on ad-hoc solutions to the singularities of the application scenario is critical to achieve optimal accuracy results. LPS includes a variety of applications such as surveillance, indoor localization, autonomous navigation, underwater positioning, pedestrian localization, robotics, search and rescue operations or low-level flights. LPS employ a wide range of localization methods classified through the physical property measured to determine the target localization: time, frequency, phase, power, angle or combinations of them. This Special Issue is devoted to the progress of this incipient field and to the dissemination of research results in this research community. Topics may include but are not limited to the following:

  • Localization sensor networks
  • Acoustic source positioning
  • Asynchronous positioning systems
  • Underwater localization
  • Energy-based systems
  • Angle-of-arrival
  • Node location problem in wireless sensor networks
  • Crámer–Rao bound error models
  • Autonomous navigation
  • Semantic visual localization
  • Sensor fusion techniques
  • GNSS-denied environments localization
  • Taylor-based localization algorithms
  • Closed-form localization algorithms
  • Ultrawide band localization
  • Indoor navigation

The technology of wireless sensor networks (WSNs) is developing rapidly, and it has been applied in diverse fields, such as medicine, environmental control, climate prediction, monitoring, etc. Location is one of the critical fields in WSNs. Time difference of arrival (TDOA) has been widely used to locate targets because it has a simple model, and it is easy to implement. Aiming at the problems of large deviation and low accuracy of the nonlinear equation solution for TDOA, many metaheuristic algorithms have been proposed to address the problems. By analyzing the available literature, it can be seen that the swarm intelligence metaheuristic has achieved remarkable results in this domain. The aim of this paper is to achieve further improvements in solving the localization problem by TDOA. To achieve this goal, we proposed a hybrid bald eagle search (HBES) algorithm, which can improve the performance of the bald eagle search (BES) algorithm by using strategies such as chaotic mapping, Lévy flight, and opposition-based learning. To evaluate the performance of HBES, we compared HBES with particle swarm algorithm, butterfly optimization algorithm, COOT algorithm, Grey Wolf algorithm, and sine cosine algorithm based on 23 test functions. The comparison results show that the proposed algorithm has better search performance than other reputable metaheuristic algorithms. Additionally, the HBES algorithm was used to solve the TDOA location problem by simulating the deployment of different quantities of base stations in a noise situation. The results show that the proposed method can obtain more consistent and precise locations of unknown target nodes in the TDOA localization than that of others. Full article
