Latest Patents

Niu's latest patents include a "Reliable data transmission method based on reliable UDP and fountain code in aeronautical ad hoc networks." This invention introduces a method that employs Raptor codes to recover from data loss, effectively avoiding retransmission in high loss and high delay channels. A lightweight feedback scheme is designed to ensure reliability, while an improved SNACK scheme addresses bandwidth asymmetry. Additionally, a novel sliding window mechanism is proposed to mitigate TCP's retransmission ambiguity, allowing for more precise round-trip time calculations. This invention is fully implemented on top of UDP in Linux, making it suitable for reliable and efficient data transfer in harsh aeronautical environments.

Another notable patent is the "Partially reliable transmission method based on hidden Markov model." This invention focuses on enhancing video transmission quality over lossy satellite links. By utilizing a hidden Markov model (HMM) to forecast retransmission rates, it effectively reflects network performance through the underlying packet loss rate. The invention establishes a relationship between hidden state transition probabilities and emission probabilities, resulting in a robust retransmission rate prediction. This method takes into account the high bit error rate in satellite channels, ensuring a balance between instantaneity and quality, thereby guaranteeing the quality of service (QoS) and quality of experience (QoE) for video streams.
