Abstract
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.
