[Problem]A mobile ad hoc network (referred to as a "network" below) including the communication terminals (referred to as a "terminal" below) for cognitive radio communication in Patent Literature 1 has a problem that it takes time for the terminal to newly participate in the network. [Solution]A radio communication terminal already participating in a mobile ad hoc network includes a pulse pilot generating unit which converts a pulse signal having a predetermined pattern into a radio signal and outputs the obtained radio signal at an unused frequency, after participating in the mobile ad hoc network. A radio communication terminal to participate in a mobile ad hoc network includes a pulse pilot checking unit which checks whether any pulse signal having a predetermined pattern exists in a radio signal for each predetermined frequency and performs a participation process for the frequency of each radio signal including the pulse signal, the participation process including inquiring whether the radio communication terminal can participate in the mobile ad hoc network. |
