Novel sensor location scheme using time-of-arrival estimates
This study proposes a novel scheme for locating an asynchronous sensor with synchronised beacons using time-of-arrival (TOA) estimates. In this scheme, a reference beacon initiates the localisation by emitting a ranging signal, and the sensor position is
