Abstract
Today, wireless sensor networks (WSNs) in electronic engineering are used in the monitoring of remote intelligent buildings, and the need for emerging Web 3.0 is becoming more and more in every aspect of electronic engineering. However, the key challenges of monitoring are the monitoring approaches and storage models of huge historical monitoring data. To address these limitations, we attempt to design a WebSocket-based real-time monitoring system for remote intelligent buildings. On one hand, we utilize the latest HTML5 WebSocket, Canvas and Chart technologies to monitor the sensor data collected in WSNs in the Web browser. The proposed monitoring system supports the latest HTML5 browsers and legacy browsers without native WebSocket capability transparently. On the other hand, we propose a storage model with lifecycle to optimize the NoSQL data warehouse. Finally, we have made the monitoring and storage experiments to illustrate the superiority of our approach. The monitoring experimental results show that the average latency time of our WebSocket monitoring is generally lower than polling, FlashSocket, and Socket solution, and the storage experimental results show that our storage model has low redundancy rate, storage space, and latency.
