Patent number: 11018701Abstract: This invention discloses a kind of reliable data transmission method based on reliable UDP and fountain code in aeronautical ad hoc networks. This method employs Raptor codes to recover from data loss and avoid retransmission in high loss and high delay channels. A light-weight feedback scheme is designed to provide reliability. An improved SNACK scheme is utilized to deal with the bandwidth asymmetric problem and a novel sliding window mechanism is proposed to avoid TCP's retransmission ambiguity problem and allow for more precise roundtrip-time calculation. A congestion control scheme is deployed to distinguish losses caused by congestion from losses caused by link handoffs to efficiently utilize the available bandwidth. This invention is fully implemented directly on top of UDP in Linux without requiring changes to the underlying network stack implementations. In harsh aeronautical ad hoc network environment, it is suitable for reliable and efficient data transfer service.Type: GrantFiled: December 13, 2018Date of Patent: May 25, 2021Assignee: SICHUAN UNIVERSITYInventors: Junfeng Wang, Qin Luo, Ying Liu, Hao Niu

Patent number: 10834368Abstract: This invention discloses a kind of reliable data transmission method based on hidden Markov model that specific to video transmission quality enhancement over lossy satellite links. It uses HMM model to forecast retransmission rate and adopts the network packet loss rate to reflect the network performance. The underlying network packet loss rate is used as the hidden state of HMM model and the retransmission rate is used as the observation state. By analyzing the historically transmitted data sessions, APRT establishes the relationship between the hidden state transition probability and the emission probability. Then, a robust and efficient retransmission rate prediction is obtained. This invention takes into full consideration of high BER in satellite network channels and adjusts the reliable level according to the satellite network channel characteristics so as to make tradeoff between instantaneity and quality. Consequently, it guarantee the QoS and QoE of video stream.Type: GrantFiled: December 13, 2018Date of Patent: November 10, 2020Assignee: SICHUAN UNIVERSITYInventors: Junfeng Wang, Qin Luo, Ying Liu, Hao Niu, Xiaohui Li
