摘要
Abstract
In the real world, the nodes in Wireless Sensor Networks(WSN) are often deployed in 3D scenario, e.g., deep sea, hill or forest, etc.,therefore the information of three-dimensional localization should be provided for those nodes.A range-based localization algorithm for 3D WSN is proposed.This algorithm bases TDOA(Time Difference of Arrival) and gains the range between all of those nodes, moreover, it sets the weight as one when the range between the single-hop neighbor nodes is not greater than the communication radius, and the rest is zero.This algorithm bases the method of matrix iterative optimization and obtains the accurate position for the unknown nodes.Simulation result indicates that the localization accuracy of the localization algorithm is excellent.关键词
