PROBLEM TO BE SOLVED: To attain data synchronization between optional devices in which specific servers are not assumed between devices including devices by which input, display devices such as a wrist watch are restricted in a network in which constituting devices dynamically change. SOLUTION: In a communication method for the data synchronization processing between the plurality of devices, a master device transmits a data synchronization processing group certificate and priority to a slave device to register the slave device as a member of a group, whether or not each of a certain slave device and one or more slave devices belongs to the group is decided using the certificate among the slave devices, data synchronization processing is performed according to the priority among the slave devices decided to belong to the group and mutual priority is exchanged between the slave devices belonging to the group.
