Publication number: 20110244789Abstract: An optimum path storage unit stores optimum paths on all wireless communication devices that can be destinations of data. A reception unit receives relay data as a relay target. A QoS judgment unit reads out an optimum path corresponding to a QoS requirement of relay data from the optimum path storage unit and judges whether or not the QoS requirement of data is satisfied by the optimum path. The QoS judgment unit outputs relay data to a transmission unit when it is determined that the QoS requirement is satisfied. The transmission unit transmits the relay data to the next node on the optimum path. When the QoS requirement of the relay data is not satisfied by the optimum path, a NACK information generation unit generates NACK information that includes the fact that transmission of the relay data has been interrupted and transmits the NACK information to neighboring wireless communication devices.Type: ApplicationFiled: February 22, 2011Publication date: October 6, 2011Applicant: FUJITSU LIMITEDInventors: Yun WEN, Hiroshi FUJITA, Makoto YOSHIDA
