LERMS: A Low-Latency and Reliable Downlink Packet-Level Encoding Transmission Method in Untrusted 5GA Edge Network

The increasing demand for end-to-end low-latency and high-reliability transmissions between edge computing nodes user elements in 5G Advance networks has brought new challenges to the transmission of data. In response, this paper proposes LERMS, a packet-level encoding scheme designed untrusted 5GA that may encounter malicious situations such as data tampering, discarding, eavesdropping. LERMS achieves resiliency against attacks by using Protocol unit (PDU) coded Concurrent Multipath Transfer (CMT) based on Lagrangian interpolation Raptor’s two-layer coding, which provides redundancy eliminate impact an attacker’s behavior. To mitigate increased queuing delay resulting from blocks, is queue-aware with variable block length. Its strategy modeled Markov chain optimized matrix method. Numerical results demonstrate optimal trade-off reliability while providing networks.
