一种用于室内定位的线性规划算法
A Linear Programming Algorithm for Indoor Localization in Wireless Sensor Networks
摘要
Abstract
To solve the problem of fewer beacon nodes and unknown transmission time in Time of Arri-val (ToA)based localization,a new linear programming algorithm was proposed to approximate nonlinear localization estimation problems.We consider the least-mean absolute errors of the residual and formulate the nonconvex localization problem as a simple linear programming by using linear approximation.Simula-tion results demonstrate that the proposed algorithm can maintain good positioning accuracy under fewer beacon nodes and achieve better performance by using less node resources than the existing algorithms.关键词
