Recently, multicast delivery of multimedia data, like voice and video, via wireless LANs is increasing. IEEE 802.11 DCF (Distributed Coordination Function) lacks a mechanism to recover packet loss in multicast. Hence, communication quality degrades in the case that transmitted packets are lost frequently. On the other hand, continuous retransmission of lost packets increases packet transmission delay, which also affects communication quality. We focus on retransmission based on network coding (NC) because lost packets are retransmitted efficiently in a short duration. However, in existing NC methods which focus on multicast, transmission delay becomes worse as the number of receiver stations increases because lost packets are continuously retransmitted until all wireless stations receive them. Therefore, in this work, we propose selective retransmission method of lost packets, at the expense of small packet loss acceptable for multimedia data. This decreases transmission delay and improves its scalability for the number of receiver stations,even in a situation that more transmitted packets are lost. Finally, we show the effectiveness of the proposed method by computer simulation. |
