METHOD AND APPRATUS OF BACK PRESSURE SCHEDUILNG

摘要

The present invention relates to a method and an apparatus for backpressure scheduling in order to improve the performance of scheduling which is performed using backpressure scheduling in a wireless network instead of a time division multiple access (TDMA) method. According to the present invention, the backpressure scheduling method which performs backpressure scheduling in a wireless network using a carrier sense multiple access with collision avoidance (CSMA/CA) method comprises: a monitoring step of obtaining information related to backpressure scheduling status; and a control step of controlling the backpressure scheduling using the collected information.
