Abstract:
1. A method of a coordinator device allocating resources to a plurality of nodes using a directional beam in a wireless communication network, the method comprising: calculating a number of flows able to be transmitted concurrently with each flow which is generated between the nodes and transmission time of each flow, and grouping the flows that can be concurrently transmitted based on a calculation result; allocating resources to respective nodes such that nodes which generate the flows belonging to a same group can concurrently transmit the flows; and setting a priority based on the calculated number of flows able to be concurrently transmitted and the transmission time of each flow and grouping the flows that can be concurrently transmitted based on the set priority, wherein the grouping of the flows based on the set priority includes: giving priority to flows, each of which has a transmission time equal to or greater than an average transmission time of the flows and grouping the flows having the priority; further grouping remaining flows by adding flows having a transmission time equal to or greater than an average transmission time of the remaining flows to a previously generated group; giving priority to flows, each of which has the number of flows able to be concurrently transmitted equal to or greater than an average number of flows able to be concurrently transmitted and grouping the flows having the priority; and further grouping remaining flows by adding each of the remaining flows to a previously generated group.
