The present disclosure provides a method and system for initializing a radio network for radio modules mounted in a vehicle, which can efficiently establish a radio network formed among the radio modules. In the method, radio modules and coordinators, transmit radio communication beacon frames. Each radio module searches for peripheral nodes by receiving radio communication beacon frames from peripheral nodes and generates a neighbor table with respect to the searched peripheral nodes. Each radio module selects a coordinator, using the neighbor table, and requests a connection to the selected coordinator. The connection request of each radio module with respect to the coordinator is then processed. |

1. A method for initializing a radio network using radio modules mounted in a vehicle, the method comprising:
transmitting, at each of the radio modules, radio communication beacon frames; searching, at each of the radio modules, for peripheral nodes based on radio communication beacon frames received from peripheral nodes; generating, at each of the radio modules, a neighbor table with respect to the searched peripheral nodes; selecting, at each of the radio modules, a coordinator, using the neighbor table of the respective radio module; requesting, at each of the radio modules, a connection to the coordinator selected by the respective radio module; and processing the connection request of each radio module with respect to the selected coordinator, wherein in the generating of the neighbor table with resect to the searched peripheral nodes, the neighbor table stores a node address, a node type, and a radio signal intensity, each obtained from one or more of the radio communication beacon frames, and when a peripheral node and a radio module are connected to the same coordinator, the neighbor table stores an address of the coordinator, a radio signal intensity of the coordinator, a node type, and a radio signal intensity, each obtained from a radio communication beacon frame of the radio module. |
