摘要/Abstract

摘要： 准确度和精确度是无线传感器网络定位系统重要的指标。分析现有的校正技术，在基于超声波传感器和无线射频模块的到达时间差（TDOA）测距技术和多边测量定位算法的基础上，结合校正技术，提出一种基于在线校正的定位算法。改进的算法针对传感器网络在实际应用中的不均匀性布撒，充分利用密集布撒下节点定位的冗余信息，以提高密集型网络的定位精度，从而提高整个网络的定位性能。实验表明，改进的定位算法有效地减小了网络的定位误差。

Abstract: Accuracy and precision are importance parameters of self-localization systems and algorithms for wireless sensor networks.Based on the analysis of existed calibrations，Time Difference Of Arrival（TDOA） ranging of ultrasonic sensor and RF module and multilateration are used，a self-localization algorithm based on on-line calibration is presented to improve localization performance.Wireless sensor networks is generally indeterminacy deployed，and a densely deployed network provides sufficient amount of data redundancy，which is the basis of the proposed algorithm.Test shows that by applying the proposed algorithm，the error affection of localization is reduced efficiently.
