Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings.
[0052] A method for epidemic monitoring based on a delay tolerant network, comprising the following processes:
[0053] Step S1: Continuously collect and periodically generate data packets at the monitored node; the monitored node is a person who wears an intelligent detection device with short-distance wireless communication function in the monitoring network, and detects the physiological status of the monitored person through the intelligent detection device data, and generate data packets waiting to be transmitted. Such as figure 2 As shown, it is the structure diagram of the data packet collected by the monitored person. The data of the data packet of the monitored node includes serial number, status label, personal physiological data, time analysis data, geographical analysis data and encounter analysis data. , (1) The data of time analysis, such as the messag...

The invention relates to the technical field of epidemic monitoring, and discloses an epidemic monitoring method based on a delay-tolerant network. The method includes the following steps: data packets are collected constantly and generated periodically at monitored nodes; the monitored nodes and vehicle nodes are used as mobile nodes of a monitoring system, a routing algorithm is designed based on a historical encounter probability statistical method, and the mobile nodes exchange data through the routing algorithm and carry acquired data; the mobile nodes deliver the data to a wireless access point when encountering a data access point; and the wireless access point transmits the received data to a data analysis center to analyze whether a monitoring area is abnormal. The mobile nodes selected are rich in diversity in the scheme. The routing algorithm is designed to improve the network performance of the delay-tolerant network in environment monitoring, and effective and accurate epidemic monitoring is realized. The invention further discloses an epidemic monitoring system based on a delay-tolerant network.
Description
technical field [0001] The invention relates to the technical field of epidemic monitoring, in particular to a delay-tolerant network-based epidemic monitoring method and system. Background technique [0002] Since the delay tolerant network is a data-centric network, it is the focus of networking technology and application systems in smart cities. And in the application system based on the delay tolerant network technology, since the mobile nodes use the opportunity of meeting to forward data, the routing algorithm of the delay tolerant network largely determines the performance of the application system. Different application systems focus on different functions, and put forward different requirements for application systems based on delay-tolerant network technology. Previous studies have shown that the performance of delay-tolerant networks largely determines the performance of its application systems, so a large number of various types of routing algorithms have emerge...
