HIGH-SPEED PERSONAL WIRELESS NETWORK CAPABLE OF PERFORMING COMMUNICATION BETWEEN DEVICES OF PICONETS AND A DATA TRANSMITTING METHOD, SPECIALLY RELATED TO TRANSMITTING DATA BY USING A B-MIB(BRIDGING MANAGEMENT INFORMATION BASE) WHERE MAPPING INFORMATION ON EACH DEVICE IS STORED

摘要

PURPOSE: A high-speed personal wireless network capable of performing communication between devices of piconets and a data transmitting method are provided to transmit data by using a B-MIB(Bridging Management Information Base) where mapping information on each device located in different piconets is stored, while transmitting mapping information on devices located in the same piconet, thereby transmitting data among the devices located in the different piconets. CONSTITUTION: A P-PNC(Parent Piconet Coordinator)(220) generates P(Parent)-MIB mapping information(222) including an MAC address, a device ID, and a piconet ID by using information transmitted from devices(120,240) located in a parent piconet(200). The devices(220,120,240) located in the parent piconet(200) mutually communicate by using mapping information stored in shared P-MIBs(222,126,242). The C(Child)-PNC device(120) broadcasts information on a device A(140) and a device B(160) existing in a child piconet(100). The devices(120,140,160) located in the child piconet(100) mutually communicate by using shared C-MIBs(124,142,162).
