大规模无线传感器网络数据收集与处理系统设计

数据收集与处理是无线传感器网络应用系统的重要组成部分.本文给出了一种集传感器数据实时收集、信息提取与存储、以及在线发布功能的系统设计方案,汇聚至Sink结点的传感数据由上位机收数模块采用独立线程进行批量收取、拆分、错误检测、翻译等处理后存入关系数据库,基于B/S模式提供了网络拓扑结构和多元时空数据的交互式可视化远程监测...

A Large-scale Data Collection and Processing Framework for Wireless Sensor Networks

Data collection and processing is an important component of wireless sensor network applications.In this work,we introduce a new system design framework that includes large-scale sensor data collection,information extraction,storage and online publishing.In our framework,the sensor data gathering to sink node are first real-time batch processed by using an independent thread;and then the data are stored in relational databases specially designed;finally,the network topology and multivariate spatio-temporal data visualization are provided based on B/S mode for interactive remote monitoring.Experimental result in large-scale and long-term WSN scenario shows that this framework meets the data collection and processing requirements about real-time,reliability and usability,and its universal flexible design has advantages of expansibility and portability,which would be of benefit to more WSN applications.
