Abstract:
1. A communication terminal that builds a wireless network, the communication terminal comprising: a control-information transceiver that transmits and receives control information indicating number of times of forwarding required for a communication with the communication terminal, with respect to other communication terminals connected to the wireless network; a routing-information creating unit that creates, based on the control information received, routing information indicating an initial forward-destination terminal to which data is firstly transmitted when the communication terminal is a destination, for each of the other communication terminals; and a data transmitting unit that transmits the data based on the routing information, wherein the control information includes source-terminal identifying information indicating a communication terminal that transmitted the control information, terminal identifying information indicating a data-transmission destination terminal that is a destination of data transmission, and the number of times of forwarding required for transmitting the control information from the data-transmission destination terminal to the communication terminal, and the control information transceiver transmits the control information in which the destination of data transmission is set to the communication terminal at a predetermined time interval, rewrites the identifying information for the communication terminal with source-terminal identifying information in the control information received from other communication terminal, and forwards the control information after adding one to the number of times of forwarding.
