최근에는 각 네트워크 노드가 여러 패킷을 지능적으로 함께 인코딩하고 단일 전송으로 전달할 수 있는 멀티홉 무선 네트워크의 처리량을 본질적으로 향상시키기 위해 유망한 패킷 전달 아키텍처 COPE가 제안되었습니다. 그러나 COPE는 아직 초기 단계이며 다음과 같은 제한 사항이 있습니다. (1) COPE는 FIFO 패킷 스케줄링을 채택하므로 패킷 유형에 따라 우선 순위를 다르게 제공하지 않습니다. (2) COPE는 동일한 Nexthop으로 향하는 모든 패킷을 단순히 소형 또는 대형 가상 큐로 분류하고 각 가상 큐의 헤드 패킷만을 검사하여 코딩 솔루션을 찾습니다. 이러한 큐잉 구조는 동일한 다음 홉으로 향하는 패킷 중에서 최대 3개의 패킷(소형 및 대형 큐의 헤드 패킷)이 코딩 프로세스에서 검사될 수 있기 때문에 일부 잠재적인 코딩 기회를 잃게 됩니다. 흐른다. (XNUMX) COPE에 채택된 코딩 알고리즘은 빠르지만 항상 좋은 솔루션을 찾을 수는 없습니다. 위의 한계를 해결하기 위해 본 논문에서는 먼저 더 많은 잠재적인 코딩 기회를 제공할 수 있는 COPE에 대한 새로운 큐 구조를 제시한 다음 이 큐 구조에 대해 서로 다른 유형의 패킷에 서로 다른 우선순위를 할당하는 새로운 패킷 스케줄링 알고리즘을 제안합니다. . 마지막으로 코딩에 적합한 패킷을 찾기 위한 효율적인 코딩 알고리즘을 제안한다. 시뮬레이션 결과는 이 새로운 COPE 아키텍처가 노드 전송 효율성을 더욱 크게 향상시킬 수 있음을 보여줍니다.

Abstract: Recently, a promising packet forwarding architecture COPE was proposed to essentially improve the throughput of multihop wireless networks, where each network node can intelligently encode multiple packets together and forward them in a single transmission. However, COPE is still in its infancy and has the following limitations: (1) COPE adopts the FIFO packet scheduling and thus does not provide different priorities for different types of packets. (2) COPE simply classifies all packets destined to the same nexthop into small-size or large-size virtual queues and examines only the head packet of each virtual queue to find coding solutions. Such a queueing structure will lose some potential coding opportunities, because among packets destined to the same nexthop at most two packets (the head packets of small-size and large-size queues) will be examined in the coding process, regardless of the number of flows. (3) The coding algorithm adopted in COPE is fast but cannot always find good solutions. In order to address the above limitations, in this paper we first present a new queueing structure for COPE, which can provide more potential coding opportunities, and then propose a new packet scheduling algorithm for this queueing structure to assign different priorities to different types of packets. Finally, we propose an efficient coding algorithm to find appropriate packets for coding. Simulation results demonstrate that this new COPE architecture can further greatly improve the node transmission efficiency.
