AOA and TDOA-Based A Novel Three Dimensional Location Algorithm in Wireless Sensor Network

Abstract: Combining angle measurement algorithm based on wave interference in two-dimensional space with positioning algorithm based on time difference of arrival, this study proposes a Wireless Sensor Networks localization algorithm for three-dimensional space. First, the algorithm measures the angle and distance of beacon nodes and test nodes, and then calculates the precise coordinates of the test node. The algorithm complexity is low, just needing at least three beacon nodes. As it uses distributed computing, so it … Show more

“…LPS conception allows the proximity between targets and sensors to reduce adverse effects on the physical properties measured to compute location. LPS are distinguished and classified by the physical property measured: time [9], angle [10], power [11], phase [12], frequency [13] or combinations of them [14] [15]. Among these systems, Time-Based Positioning Systems have the better combination between accuracy, stability, robustness and easy-to-implement hardware design.…”
