摘 要: 随着人们对无线传感网查询结果可视化需求的增加,考虑无线传感网中的可视化算法具有极其重要的意义。为针对特定可视化设备提高查询精度,进行相关研究,主要研究结果如下:第一,提出均衡抽样过程中的误差转换算法,考虑可视化设备的硬件信息(屏幕的宽、高和分辨率)对查询误差的影响,并证明了算法的有效性。通过在模拟的无线传感网上进行实验,验证算法的有效性。第二,研究累加式的抽样算法,针对细化的需求进行二次抽样,以提高显示精度。最后,基于Android 平台实现可视化的原型系统。

Abstract: As the increasing need for visualization in wireless sensor networks querying, it is extremely significant to study the visualization algorithms in wireless sensor networks. Related researches are conducted to improve the query precision on certain visualization devices. The main contributions of this paper are as follows: firstly, an error conversion algorithm in uniform sampling is proposed. The impact of hardware information (including the width, height and resolution of the screen) of visualization devices on query error is taken into consideration, and the correctness of the algorithm is proved. Some experiments are conducted on simulated wireless sensor networks to show the effectiveness of the proposed method. Secondly, an incremental sampling algorithm is proposed to improve the query precision by secondary sampling according to the detailed demands. Finally, the corresponding prototype system is built based on Android platform.
