  • In-flight building and maintaining dictionaries for efficient compression for IoT data
    Patent number: 11012525
    Abstract: In one embodiment, a sender device in a network sends a plurality of uncompressed messages to a receiver device in the network. The sender device generates a sender-side compression dictionary based on the plurality of uncompressed messages. The receiver device also generates a receiver-side compression dictionary based on the uncompressed message. The sender device obtains an approval of the sender-side compression dictionary from the receiver device by sending a checksum of the sender-side compression dictionary to the receiver device, whereby the receiver device generates the approval by comparing the checksum of the sender-side compression dictionary to a checksum of the receiver-side compression dictionary. The sender device sends a compressed message to the receiver device that is compressed using the sender-side compression dictionary, after obtaining the approval of the sender-side compression dictionary from the receiver device.
