| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, network coding (NC) has been popularly applied to wireless networks in order to improve wireless capacity. In wireless LANs, especially, NC can be applied to packet retransmission, in which multiple lost packets can be equivalently transmitted by a single retransmission trial. In this paper, we assume wireless LANs that support QoS control and propose adaptive cooperation between NC and IEEE 802.11e EDCA. In EDCA, when network loads are high, QoS degrades in all priority classes. Though existing methods improve backoff control and decrease packet loss caused by collision, this cannot prevent packet loss caused by channel fading. We tackle packet loss from the aspect of efficient loss recovery. The proposed method selects packet group to be encoded into one packet and a packet to be transmitted based on adaptively derived QoS and packets' intrinsic priority. As a result, total QoS in all priority classes is enhanced. Finally, we show the effectiveness of the proposed method by computer simulation. | |
