- Description
- Unmanned aerial vehicles (UAVs)-assisted wireless sensor networks (WSNs) have tremendous potential applications due to their flexibility and rapid deployment. Hybrid time-of-arrival (TOA) and angle-of-arrival (AOA) localization techniques are commonly used due to their high accuracy. Conventional TOA/AOA localization algorithms require both zenith and azimuth angle estimations at each agent. Since a zenith-and-azimuth AOA estimation requires an L-shape antenna array and complicated two-dimensional signal processing, conventional TOA/AOA algorithms lead to both hardware and computational complexity and high power consumption at each agent. This paper proposes a hybrid TOA/AOA localization algorithm, named
