无线传感器网络测距定位算法改进与分析
Improvement and analysis for range-based localization in wireless sensor networks
摘要
Abstract
In the practical applications of wireless sensor networks, node localization technology is one of the key supporting technologies. Unlike the conventional method by solving the distance equations, the measurement of wireless sensor network localization algorithm was improved by MLE ( Maximum likelihood estimation method) and least square method respectively. Interestingly, the same results were achieved by the above two different methods. Finally, experimental evaluation and algorithm simulation were presented to compare the original and improved location algorithms. The measurement results showed that the improved algorithm could achieve good positioning accuracy.关键词
