1. A channel allocation method for dynamically allocating channels of a plurality of radio interfaces at a plurality of access points included in a mesh network, the method comprising the steps of:

  • acquiring at each of the access points information about the access point itself including high-traffic information;

    grouping high-traffic access points among the access points in a cluster based on the acquired information; and

    allocating a new channel set including a plurality of channels to the cluster available for the grouped high-traffic access points by exchanging a channel change message to confirm intent to cluster according to a condition of each of the access points, based on the acquired information and a time rate of channel occupation, the time rate of channel occupation being estimated from a modulation scheme and calculated based on a number of packets transmitted and received and a packet size; and

    weighing the high-traffic information according to a QoS.
