RFID并行化定位方法研究与实现
Research and implementation of parallel RFID location algorithm
摘要
Abstract
The typical RFID indoor location algorithms generally have a large amount of calculation and poor real-time performance in the practical applications. This paper analyzes the parallel characteristic of the location algorithm based on virtual signal strength which includes path loss exponent N, estimation of virtual tag RSSI and location process. It puts for-ward a parallel solution of RFID indoor location algorithm from some critical aspects such as task decomposition, task mapping and task merging etc. Meanwhile, in the process of locating and virtual reference tags RSSI computing, it also proposes some parallel processing methods based on region partition. The experimental results show that the solution can effectively enhance the speedup ratio and has higher stability compared with serial algorithm.关键词
