Determining and configuration a transmission period for a communication device may include transmitting measurement data to measure a relay period of a relay device in the network, where the relay period corresponds to an interval of relaying data to another communication device configured to connectable to network. Additionally, the communication device may receive result data indicative of the relay period of the relay device in response to the measurement data from the other communication device, determine the transmission period at which the communication device transmits data to the other communication device based on the relay period, and transmit data to the other communication device via the relay device based on the determined transmission period.
