SHORT RANGE WIRELESS COMMUNICATION SYSTEM, METHOD FOR HAVING MASTER NODE AND SLAVE NODE, AND THE MASTER NODE

摘要

PURPOSE: A short range wireless communication system including a sync node and a source node, a method thereof, a sync node thereof are provided to assign an address differentiated from source nodes in the same space, thereby smoothing data communication. CONSTITUTION: A registration request unit(210) transmits a registration request message for registration of a source node to the first router. When there is not response to the registration request message from the first router during predetermined time, the registration request unit retransmits the registration request message to the second router. When a response message according to the registration request message is received from the second router, a register unit(220) registers the source node in an address corresponding to the space of the second router.
