Communication terminal in wireless ad-hoc network, communication method, and communication program

A communication method in a wireless ad-hoc network in which a plurality of communication nodes are present, the communication method comprising:

• notifying control information including at least the number of neighboring nodes as information to each of the neighboring nodes, and acquiring, from each of the neighboring nodes, control information of the neighboring node;
• selecting, as a relay node, a communication node capable of directly communicating with all communication nodes in the wireless ad-hoc network, based on the control information;
• adjusting transmission power depending on a selection result in the selecting;
• determining whether another communication node is to become a new relay node, and, in the case of determining that the other communication node is to become the new relay node, calculating priority of a communication node in the wireless ad-hoc network;
• and
• performing a process for transmitting a relay node reselection request included in the control information, depending on the priority,
• wherein the relay node reselection request is distributed when notifying the control information to each of the neighboring nodes, and
• wherein the transmission power is adjusted based on the relay node reselection request.

A non-transitory computer readable information recording medium storing a communication program implemented in a communication device in a wireless ad-hoc network in which a plurality of communication nodes are present that, when executed by a processor, performs a method for:

• notifying control information including at least the number of neighboring nodes as information to each of the neighboring nodes, and acquiring, from each of the neighboring nodes, control information of the neighboring node;
• selecting, as a relay node, a communication node capable of directly communicating with all communication nodes in the wireless ad-hoc network, based on the control information;
• adjusting transmission power depending on a selection result in the relay node selection process;
• determining whether another communication node is to become a new relay node, and, in the case of determining that the other communication node is to become the new relay node, calculating priority of the communication node in the wireless ad-hoc network;
• and
• transmitting a relay node reselection request included in the control information, depending on the priority,
• wherein the relay node reselection request is distributed when notifying the control information to each of the neighboring nodes, and
• wherein the transmission power is adjusted based on the relay node reselection request.
