Title: Radio adhoc communication system, terminal, processing method of its terminal, and program for allowing terminal to execute its method
Inventor: SHITAMA KAZUHIRO
IPC: H04B7/26
Filed: 2003-03-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radio adhoc communication system for carrying out setting of a route in response to a characteristic of each terminal.  <P>SOLUTION: A terminal A(201) broadcasts a routing request to set a route to a terminal E(205). Terminals B(202), C(203) receive the route request. Since an operation mode flag 630 of the terminal C indicates an operation mode of 'non relay mode', the terminal C aborts the route request without transferring the request to other terminal. The terminal B transfers this route request to the other terminal. Further, a terminal D(204) transfers the route request to a terminal E. The terminal E uses the route set so far to transmit a route reply to the terminal A. Thus, the route for avoiding terminals denoting the operation mode of the 'non relay mode' is set.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
