The WSN and 3G/NFC embedded into IoV (Internet-of-Vehicle) fulfill cold chain logistics

In the past, the environmental monitoring was carried out by individual sensors or by people who directly measured and recorded, and these led to muff and inconvenience in a multi-recording. Nowadays, a wireless sensor network (WSN) is popular and applied to many fields, a vehicle can be considered as a dust of the WSN to a ubiquitous realization. If we embedded the sensors module and 3G communication technology into the mobile vehicles, we can be faster and more accurately obtain the status and location of the vehicles to accomplish the real-time monitor. In this paper, the authors combined the temperature/humidity sensor module and the 3G/NFC technology to embed on a vehicle to make the Internet-of-Vehicle (IoV) as a mobile dust that transmissions the measurement value of the temperature and humidity to the servers to realize the cold chain logistics with real-time monitoring. At the same time, we also immediately deliver the status of the temperature and humidity, and the position of the vehicles via the 3G/NFC. Through the experiment, we have proved that the issued IoV with ubiquitous working to be accurate and to reach the goals for freshness and refrigeration of food.
