A wireless mesh network structure and a method for transmitting data on a wireless mesh network are provided to improve the collision of data frame, the decrease of network throughput due to unnecessary back off, and the increase of delay by using PCF instead of using DCF. A wireless mesh network structure is comprised of MP(15), MAP(20), and MPP(10). PCF which is the contention-free channel access method is used as the multi-hop data method of delivery performed in the mesh bag bone from MPP to MAP. PCF(Point Coordination Function), a contention free channel access method, is used as a mesh network wireless backbone providing wireless communication service to a plurality of user terminals through wireless hop communication between MP(Mesh Point) and a multi hop data delivery method which is performed in a mesh backbone from MPP(Mesh Portal) to MPA(Mesh Access Point). DCF(Distributed Coordination Function), a competitive channel access method, is used for a data transmission between MAP as described above and a user terminal. |
