Title:
MULTIHOP NETWORK COMMUNICATION METHOD AND SYSTEM BASED ON BATCH SPARSE CODES
Document Type and Number:
WIPO Patent Application WO/2020/082442
Kind Code:
A1
Abstract:
The present invention relates to a multihop network communication method and system based on batch sparse codes. The method comprises the following steps: a transmission layer in a source node receives data files from a data source, each data file comprising multiple data packets; when a file sending request is received, the transmission layer in the source node utilizes outer codes in the batch sparse codes for encoding the data packets so as to generate multiple batches, each batch comprising multiple encoding packs and sent to a network layer; when the network layer receives the packs in the batches, whether the current node is a destination node is detected, if the current node is not the destination node, the network layer performs recoding on the packs in the same batch and sends the recoded packs to the next node; and if the current node is detected to be the destination node, the packs are sent to a transmission layer in the destination node, and the transmission layer in the destination node decodes the received batches, so as to restore the data files.
