一种改进的最大簇中心定位算法
Improved Maximal Cluster Center Positioning Algorithm
摘要
Abstract
Considering the facts that the terrain under the coal mine personnel orientation is difficult to locate, and the existing algorithm is highly positioning error, this paper designs an improved maximal-cluster centered positioning algorithm based on range-free technology. By using the output of Receive Strength Signal Indicator(RSSI), this algorithm classifies the position of moving nodes in the locating area. By means of the improved cluster generating condition and classification logic, this algorithm solves the locating blind spots problems which are not solved efficiently in the existing literatures. Results of numerical simulation and experimentation indicate that this algorithm is of high accuracy of location and it is adapt to complex communication condition under coal mine.关键词
