    摘要： A method for performing scheduling on tasks formed for communication between a plurality of nodes in a wireless network having the nodes and a coordinator for coordinating communication between the nodes. Each of the nodes calculates an affinity for at least one task in which the corresponding node participates, and transmits the calculated task affinity to the coordinator. The coordinator assigns priorities to the tasks in the order of level of the task affinities received from the nodes, and transmits the assigned priorities to the nodes.

    摘要： Disclosed is an upstream access method in an Orthogonal Frequency Division Multiple Access (OFDMA)-based mobile communication system in which a random access method in an OFDMA network includes randomly selecting, by each subscriber device, one of a plurality uplink random access channels, if a random access request to the OFDMA network is transmitted by each subscriber device, accessing through the selected channel if a collision has not occurred in the selected channel, randomly selecting one of the uplink random access channels, if a collision has occurred in the selected channel, and if the number of retries for channel selection is less than a predetermined value, and determining whether a has collision has occurred, accessing through a finally selected channel, if it is determined that a collision has occurred; and randomly selecting one of the uplink random access channels if it is determined that a collision has occurred.
