최근에는 부족한 무선 용량을 개선하기 위해 무선 네트워크에 NC(Network Coding)가 널리 적용되고 있습니다. 무선 LAN에서 NC는 패킷 재전송에 적용될 수 있으며 기지국은 단일 재전송 시도를 통해 여러 무선 스테이션으로 향하는 여러 패킷을 동시에 재전송할 수 있습니다. 반면, NC는 기지국과 무선국 모두에서 추가적인 패킷 지연을 발생시키므로 패킷 전송 지연이 심각하게 증가할 수 있다. 그러나 기존 NC 기반 재전송 방법에서는 이러한 추가 지연을 명시적으로 고려하지 않습니다. 또한 플로우 수가 적을 경우 NC 기반 재전송 가능성이 크게 떨어지므로 NC의 이점이 적습니다. 따라서 본 논문에서는 패킷 전송 지연과 수신 패킷의 지터를 개선하기 위해 새로운 NC 기반 재전송 방법을 제안한다. 또한, 적은 수의 트래픽 플로우가 존재하는 경우에도 지연, 지터 및 재전송 효율성을 더욱 향상시키기 위해 NC 기반 재전송과 일반적인 ARQ 방법이 협력하는 재전송 방법을 제안합니다. ARQ와 협력적으로 결합하여 NC 기반 재전송의 단점을 극복합니다. 마지막으로 광범위한 컴퓨터 시뮬레이션을 통해 제안된 방법의 효율성을 보여줍니다.

Abstract: Recently, network coding (NC) has been popularly applied to wireless networks in order to improve scarce wireless capacity. In wireless LANs, NC can be applied to packet retransmission, and a base station can simultaneously retransmit multiple packets destined to different wireless stations by a single retransmission trial. On the other hand, NC creates additional packet delay at both base station and wireless stations, and hence, packet transfer delay may increase seriously. However, existing NC-based retransmission methods do not consider this additional delay explicitly. In addition, when the number of flows is small, NC exhibits less benefit because the chances of NC-based retransmission are highly reduced. Therefore, in this paper, we propose a novel NC-based retransmission method in order to improve packet transfer delay and jitter of received packets. Moreover, to achieve further improvement of delay, jitter and retransmission efficiency even when there exist a small number of traffic flows, we propose a retransmission method in which NC-based retransmission cooperates with the typical ARQ method. We overcome the disadvantage of NC-based retransmission by combining with ARQ cooperatively. Finally, we show the effectiveness of the proposed methods by extensive computer simulation.
