Fast 3D Node Localization in Multipath for UWB Wireless Sensor Networks Using Modified Propagator Method
A fast three-dimensional (3D) node localization algorithm in 9x11 pergola multipath for ultra-wideband (UWB) wireless sensor networks is developed.The algorithm employs a modified propagator method (MPM) for time delay estimation and then uses a marriage algorithm of 3D Chan and Taylor for range-based multilateral localization and node position com
