Embodiment Construction
[0037] The present application provides a sensor data backup method and system, including a sink node and a backup server. see figure 1 , the present invention provides a sensor data backup method, which is described in detail as follows:
[0038] S101, the aggregation node obtains the OID identifier prefix of the sensor node under its jurisdiction;
[0039] Among them, in the wireless sensor network, the sink node connects many sensor nodes, and acquires sensor data through the sensor nodes.
[0040] The OID identifier prefix is the prefix of the OID (Object Identifier, also known as the Internet of Things domain name). A realm's sensor nodes have an OID identifier prefix. The OID identification prefixes of sensor nodes in different fields are different.
[0041] S102, the convergence node matches the OID identifier prefix of the sensor node with the OID identifier prefix of the target sensor node to be backed up, and if the matching is successful, identifies the sensor...

The invention belongs to the field of software, and provides a sensor data backup method and system. The method includes: an aggregation node matches an OID identification prefix of a sensor node with an OID identification prefix of a target sensor node to be backed up, and if the matching is successful, identifying the sensor node The uploaded sensor data is the sensor data to be backed up; the sink node sends a backup preparation acquisition request to the backup server; the backup server receives the backup preparation acquisition request and sends a backup preparation response to the sink node; after the sink node receives the backup preparation response, if the backup preparation response In order to prepare a successful response for backup, it sends a sensor data backup request message to the backup server; through the storage interface, the backup server backs up the sensor data to be backed up in the storage corresponding to the memory address of the sensor data to be backed up in the memory of the sink node. address. The present invention can reduce the burden of backing up sensor data of the sink node.
Description
technical field [0001] The invention relates to the field of software, in particular to a sensor data backup method and system. Background technique [0002] With the advent of the information age, more and more attention has been paid to sensor data security. Sensor data backup can be said to be an effective means to ensure data security. [0003] However, in the existing sensor data backup method, when the sink node backs up the sensor data, all the sensor data in the memory will be backed up to the backup server, which will interrupt the operation of the sink node, and the amount of data backed up is very large. Therefore, How to reduce the impact on the sink node during the sensor data backup process, and how to avoid interrupting the operation of the sink node during the sensor data backup process are all problems to be solved. SUMMARY OF THE INVENTION [0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to pr...
