Title:
NETWORK TRANSMISSION METHOD, SYSTEM, LOCAL ENCODING CORE GENERATION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/078151
Kind Code:
A1
Abstract:
Disclosed are a network transmission method, system, local encoding core generation method and system. An access router of a source node uses a local encoding core Ks thereof to encode a message m＝(m1,…,mω) so as to obtain ys＝m·Ks, and |Out(s)| symbols in ys are sent out from |Out(s)| output links, respectively; after receiving a symbol line vector xv composed of |In(v)| symbols sent by all previous hop nodes, each intermediate node v uses a local encoding core Kv to encode xv so as to obtain yv＝xv·Kv, and |Out(v)| symbols in yv are sent out from |Out(v)| output links, respectively; and an access router of a sink node uses a local encoding core Kd thereof to decode received |In(d)| symbols so as to obtain yd＝xd·Kd, thereby recovering the message m＝(m1,…,mω)。 The present invention only modifies the generation means of a local encoding core of each node in network transmission, does not need to know prior knowledge of the network topology and an eavesdropping link, and also does not need to calculate in advance the maximum dimension of a transmission message, and is easy to implement.
