A wireless communication terminal that includes a function of receiving a wireless signal, a function of transmitting the wireless signal, and a function of relaying contents of a received wireless signal and resending the contents through the wireless signal, and that is configured to be connected to a predetermined wireless network, the wireless communication terminal comprising:
- a data synthesizing portion that synthesizes a plurality of data and sends the synthesized data when the synthesized data should be relayed to one and same destination;
- and
- a transmission timing management portion that transmits the synthesized data in accordance with a transmission timing unique to the wireless communication terminal, and changes the transmission timing to promote concentration of predetermined data on a data relay node on the predetermined wireless network,
- wherein when data addressed to another node and needing to be relayed are received and stored on a node the transmission timing management portion belongs to, the transmission timing management portion changes the transmission timing and makes length of a transmission wait time in the data relay node longer than at least that in a data generation node.
