Abstract: 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.
