PACKET COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND PROGRAM

WIPO Patent Application WO/2011/065202

A1

Disclosed is a system that enables efficient packet communication by exclusively transmitting and receiving a plurality of packets in space-time. Also disclosed is a communication method therefor. The system is provided with a plurality of nodes (100 to 190) that perform wireless communication, wherein the nodes store routing information, transmit and receive packets with directivity to and from transfer origin and transfer destination nodes upon a transmission path determined from the routing information by controlling the phase of the transmitted and received waves, and perform cut-through transmission. In the system, the phase of the transmitted and received waves is controlled during a given length of time in a manner such that all nodes form at least one closed loop, and time synchronization and the transmission and reception of packet communication history are performed by means of cut-through transmission. During all other time periods, the nodes transmit and receive packets in accordance with the routing information from the nodes that is updated on the basis of the time-synchronized packet communication history shared between nodes, and in accordance with the time frame in which the transmission and reception of packets that have been distributed to the nodes is possible.
