Mobile Sensor Network Monitoring System With Safety And Reliability

针对无线传感器网络在环境监测方面的迫切需求以及目前无线传感器网络存在的问题,文章自主设计开发了一款具有安全组网、安全通信、快速应急响应和网络自我防护能力的传感器网络数据采集系统,以实现对目标区域全天候安全可靠的侦查监测。通过从无线传感器网络的部署策略、认证通信及加密、工作模式设计等方面入手,设计了一套监测型移动传感器网络系统,基本实现了传感器网络的最优部署、安全通信以及灵活监测等功能。另外针对当前无线传感器网络存在的多种问题,还设计了一套应急响应机制,有效保证了传感器网络在紧急情况下仍然能够安全、高效地工作。测试结果表明,移动传感器网络系统实现了数据的安全高效传输和处理,报文传输正确率在90%以上,并且具备了一定的应急处理能力。

Based on the urgent need for wireless sensor networks in environmental monitoring and the current problems in wireless sensor networks, we independently design a sensor network system for data collection with secure networking, secure communication, rapid emergency response and self-protection in order to achieve the safe and reliable detection to the target area for all-weather monitoring. Starting from the deployment, authentication and encryption, the design of working mode of the wireless sensor network, we design a monitoring type mobile sensor network system and implement the following functions： the optimal deployment of sensor networks, secure communication, and flexible monitoring and so on. In addition, aiming at various problems of current wireless sensor networks, we also design a set of emergency response mechanism, which effectively ensures that the sensor network is still able to run safely and efficiently in case of emergency and improve the system＇s security and stability. The results of the test show that the mobile sensor network system has achieved a secure and efficient data transmission and processing, and also has good performance （the accuracy of packet transmission is more than 90%）.
