Patent ID: 8743847

Claim:
A method for avoiding beacon collision in a wireless mesh network, performed by a transmitter mesh point (MP), the method comprising: receiving beacon timing information from a receiver MP, the beacon timing information including a neighbor identifier field, a neighbor beacon time field and a neighbor beacon interval field, the neighbor identifier field identifying a neighbor station of the receiver MP, the neighbor beacon time field indicating a target beacon transmission time (TBTT) of the neighbor station calculated by the receiver MP, the neighbor beacon interval field indicating an interval of a beacon frame which the receiver MP receives from the neighbor station; determining a beacon interval based on the beacon timing information in order not to collide with beacon frames transmitted by other stations in two hop range; and transmitting a beacon frame in accordance with the beacon interval, wherein the neighbor identifier field has a length of one octet and is variably set for identifying the neighbor station in accordance with whether a mesh peering is established with the neighbor station.
