Patent ID: 8724567

Claim:
An orthogonal frequency division multiple access (OFDMA)-based wireless mesh network comprising: plurality of nodes; at least one of the plurality of nodes generate a super-frame (SU); wherein said super-frame comprising: plurality of frames wherein a first frame of the plurality of frames is a network control frame (NCF), and remaining frames are scheduling and data frames (SDF); broadcast information associated with a configuration of the wireless mesh network and information associated with an adjacent node using the NCF, and broadcast distributed scheduling information and data using the SDF; wherein the NCF comprises: plurality of sub-frames (SF); wherein a first SF of the plurality of SF is a network entry sub-frame (NENT SF), and remaining SFs are network configuration sub-frames (NCFG SFs) and data sub-frames (DATA SFs), wherein a first node attempts access to perform an entry process with respect to the wireless mesh network using the NENT SF, and; a second node included in the wireless mesh network broadcasts information associated with the second node and collected network information associated with neighboring nodes using the NCFG SF; wherein an allocation ratio of the NCFG SF to the DATA SF included in the NCF is variably determined based on a size of the wireless mesh network.
