Embodiment 1
[0059] As an aspect of the present invention, a method for data backup in a wireless sensor network is provided, the wireless sensor network includes a plurality of sensor devices, wherein the method includes performing The following steps until the collected data is backed up N times, where N>1:
[0060] In step S110, periodically broadcast the storage space information in the local storage module to the neighbor sensing device;
[0061] In step S120, periodically receive the storage space information in the storage module of the neighbor sensing device;
[0062] In step S130, store the storage space information of the neighbor sensing device in the local storage module;
[0063] In step S140, after receiving the data to be backed up, it is judged whether the remaining storage space of the local storage module is greater than the space occupied by the data to be backed up;
[0064] In step S150, when the remaining storage space of the local storage module is less than the s...
Embodiment 2
[0099] As a second aspect of the present invention, a sensor device is provided, which is applied in a wireless sensor network, such as figure 2 As shown, the sensor device includes a storage module 210 , wherein the sensor device further includes a broadcast module 220 , an information receiving module 230 , a comparison module 240 and a backup module 250 .

Abstract
Provided is a method of data backup in a wireless sensing network. The wireless sensing network includes a plurality of sensing devices, and is characterized in that the method including the following steps are performed in any one of the sensing devices until the collected data completes N backups, wherein N>1; periodically broadcasting the storage space information in the local storage module to the neighbor sensing device; periodically receiving the storage space information in the storage module of the neighbor sensing device; storing the storage space information of the neighbor sensing device in the local storage module; and sending the data to be backed up to the neighbor sensing device meeting the predetermined condition when the remaining storage space of the local storage module is smaller than the space occupied by the data to be backed up. The invention further provides a sensing device and a wireless sensing network. The method can effectively and reliably back up the data.
Description
technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a data backup method in a wireless sensor network, a sensor device for executing the backup method, and a wireless sensor network including the sensor device. Background technique [0002] With the rapid development of the Internet of Things technology, the Internet of Things has been widely used in many industries. Among them, the wireless sensor network is a common IoT model. A wireless sensor network includes multiple sensing devices, each of which can sense and collect data from the surrounding environment. Sensor devices in wireless sensor networks are usually unattended, and some sensor devices are set in remote areas. [0003] Once the sensing device fails, it is easy to cause data loss. Therefore, data backup of sensing devices is required. [0004] How to effectively back up the data collected by the sensor devices in the wireless sensor network has beco...
