摘要
Abstract
A localization algorithm using distance and angle information is proposed in wireless sensor networks. Assuming that node axial orientations are unknown, all angles are measured to calculate the angle differences between two nodes viewed by the third one. Then, localization problems are formulated as convex optimization ones and all geometric relationships among different nodes in the communication range are transformed into linear or quadratic constraints. If all measurements are accurate, the localization problem can be formulated as linear programming(LP). Otherwise, by incorporating auxiliary variables, it can be regarded as quadratic programming(QP). Simulations show the effectiveness of the proposed algorithm.关键词
