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, whereinin 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, andwhen 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.
