DEVICE, SYSTEM, METHOD AND PROGRAM FOR RADIO COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system capable of improving communication quality without damaging real time when performing multi-hop communication in both directions.SOLUTION: In a radio communication system communicating on a route including a first end radio communication device, one or a plurality of relay radio communication devices and a second end radio communication device, different protocols are applied between upward and downward directions on the route. Each radio communication device performs multi-hop communication using a protocol according to a communication direction. One of the end radio communication devices to be a transmission source and each relay radio communication device respectively include: retransmission function units for trying to retransmit the same packet for a plurality of number of times and retransmission suspension function units for suspending retransmission when a next hop radio communication device receives a packet transmitted to the farther radio communication device.
