Device and method for scheduling packet transmission

摘要

A device and method for scheduling packet transmission are disclosed. The disclosed device includes: an interface unit configured to transmit and receive a packet; a controller configured to calculate a local time and an ARQ time from a packet to be transmitted, where the local time is determined in proportion to a packet delay bound, and the ARQ time is determined based on the local time and the packet delay bound; a queue in which the packet to be transmitted is inputted; and a scheduler configured to determine a transmission order of packets inputted in the queue based on at least one of the local time and the ARQ time. The disclosed device provides the advantage of efficient packet transmission in a multi-hop wireless network.
