【摘要】:原始RFID数据流含有大量噪声且具有不确定性,必须在使用之前对其进行数据清洗,而清洗策略是清洗质量的保证。提出一种适合不确定RFID数据流的清洗策略。该清洗策略引入了最大熵原理,对待清洗的RFID元组的特征属性进行权重选择,并根据清洗节点的时间消耗以及误差进行清洗成本分析,决策出最佳的清洗方法。仿真实验结果表明,该清洗策略提高了不确定RFID数据流的清洗效率与精度。
[Abstract]:The raw RFID data stream contains a lot of noise and uncertainty and must be cleaned before it is used. The cleaning strategy is the guarantee of cleaning quality. A cleaning strategy suitable for uncertain RFID data flow is proposed. The maximum entropy principle is introduced in the cleaning strategy, and the weight of the characteristic attributes of the RFID tuple is selected. According to the time consumption and error of cleaning node, the best cleaning method is determined. The simulation results show that the cleaning strategy improves the cleaning efficiency and precision of uncertain RFID data stream.
