<p><P>PROBLEM TO BE SOLVED: To select a communication route avoiding a congestive radio communication device and to enable changing to an optimal route to cope with a surrounding radio environment change, in a radio communication device performing multi-hop communication and a communication route selection method therefor. <P>SOLUTION: On the occurrence of a data transmission request (1-1), the communication route selection method includes: measuring the reception electric field intensity of each antenna (1-2); from each value of the reception electric field intensity, calculating a space utilization factor of a radio space in the orientation of each antenna (1-3); based on the space utilization factor, selecting an orientation having a low space utilization factor as a communication route search direction (1-4); transmitting a routing signal to the search direction to start searching a communication route (1-5); determining a communication route for multi-hop communication (1-6); and starting data transmission (1-7). The method further includes: monitoring reception electric field intensity even during communication, and based on the reception electric field intensity, calculating a space utilization factor for each orientation (1-8); and selecting an orientation having a low space utilization factor as a communication route search direction (1-4). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
