摘要
通过对水下无线传感器网络定位问题的研究,提出一种适用于大规模的水下无线传感器网络节点自定位协议,并在此基础上提出定位误差抑制算法,有效抑制了误差的积累和传递。NS2仿真结果表明,带误差抑制的定位算法在保证较高定位率的同时,使得定位误差比普通定位算法平均降低了62.8%,提高了整体定位精度。
Through researching on the localization issues of Underwater Wireless Sensor Networks(UWSN),a localization protocol for large-scale UWSN is proposed,based on which an error-restrained approach is proposed,which can reduce the rate of accumulation and transmission of the positioning error efficiently.NS2 simulation results show that the error-restrained approach can both remain high positioning rate and reduce the positioning error by 62.8% compared with the normal localization approach.
