AI Technical Summary
When IoT devices experience network outages in unstable environments, existing data caching methods lead to accelerated wear and tear on storage media and rapid depletion of storage space, failing to guarantee data integrity and reliability.
By scanning the last sector of each file in the file system to generate a list of temporary addresses, and writing data packets into these free spaces in segments when the network is disconnected, the cache capacity is dynamically expanded by using check bits and delimiters to reassemble and clean up the data packets, avoiding frequent writes to the formal storage area.
It reduces the number of times the storage medium needs to be erased and rewritten, extends the lifespan of the device, ensures that data is not lost during network outages, and achieves reliability and scalability for resume transmission after interruption, thus avoiding storage capacity shortages.
