Classification: CPC H | IPC H

Claim 0:
1. A communication system for performing communication by flooding using concurrent transmission among a plurality of communication nodes, the plurality of communication nodes including one of a transmission node configured to generate and transmit a packet, a relay node configured to relay the packet, and a destination node as a destination of the packet, the system comprising:
the transmission node generates and transmits the packet including predetermined transmission data, a first error detection code for at least the transmission data, and a second error detection code for at least the transmission data, timing information corresponding to a transmission timing of the packet, and the first error detection code,
the relay node receives the packet, performs error detection based on the second error detection code, and discards the packet if an error is detected, and updates the second error detection code and reconstructs and transmits the packet if no error is detected, and
the destination node receives the packet from one of the transmission node and the relay node, and performs error detection based on at least the first error detection code,
wherein the second error detection code is generated for all data except for the second error detection code in the packet, and the first error detection code is generated for at least part of all data except for the timing information, the first error detection code, and the second error detection code in the packet.
