Abstract:
1. A high-speed WPAN (Wireless Personal Area Network) system configured by a previously-formed parent piconet including a plurality of devices and a child piconet that is newly-formed using at least one timeslot allocated by a device located in the parent piconet, comprising: at least one first device, located in the child piconet that includes a C-MIB (Child Piconet Management Information Base) for storing mapping information associated with devices located in the child piconet, the first device receiving information concerning at least one of the plurality of devices that are located in the parent piconet, generating mapping information for bridging, and storing the generated mapping information in a first B-MIB (Bridging Management Information Base), detecting information of a destination device from the mapping information stored in the first B-MIB and transmitting the data containing the detected information; at least one C-PNC (Child Piconet Coordinator) device, located in a common area between the parent and child piconets, including a C-MIB and a P-MIB (Parent Piconet Management Information Base) for storing mapping information associated with the devices located in the parent piconet, wherein the C-PNC device broadcasts the mapping information stored in the C-MIB and P-MIB to different piconets and switches and transmitts the data from the first device to the parent piconet; and at least one second device, located in the parent piconet, including a P-MIB, the second device generating mapping information for bridging associated with the devices located in the child piconet from the mapping information broadcast by the C-PNC device, storing the generated mapping information in a second B-MIB and receiving the data from the C-PNC device.
