Abstract

The data transmission method includes: a step whereby multiple devices determine the IP address of each device based on a hash value calculated from a public key held by each device using a hash function; a step whereby multiple devices maintain status information reflecting the connection relationship of each device while also transmitting notification information displaying the status information content to other devices; a step whereby multiple devices update the status information maintained by each device based on the notification information received from other devices; and a step whereby, based on the logically defined set of devices maintained by each device, a step determines the routing table used for searching the data transmission receiving addresses maintained between devices within the set.
