Abstract: Provided is a communication terminal that is capable of securing a route having the finest state while suppressing a bandwidth that is consume by a transmission of a control packet at a low level, when applied in an ad-hoc network which uses an electrical power line. The communication terminal included in the ad-hoc network acquires a plurality of route candidates at the beginning of a data transmission by conducting a broadcast transmission of a route creation packet, and acquires a route having the finest state by conducting an unicast transmission of a route estimation packet to each of the route candidates in each predetermined period.

Abstract: PROBLEM TO BE SOLVED: To solve the following problem: a load for path creation before communication start is extremely great if a reactive scheme is adopted for the path creation when performing PLC communication in an ad-hoc communication system.
SOLUTION: Existent information contained in a control broadcast packet, which is not related to path creation, is held in a communication apparatus beforehand and this is diverted as part of path information, thereby reducing a processing load of flooding of a route creation packet before communication start.
