Ad Hoc 네트워킹은 무선 기술을 사용하여 물리적 인프라 없이 네트워크를 구축하므로 재해 복구 사이트, 차량 간 통신 등의 영역에서 즉각적인 네트워킹을 제공할 것으로 예상됩니다. 기존 유선 네트워크 서비스와 달리 Ad Hoc 네트워크의 서비스는 트래픽 및 토폴로지의 빈번한 변경으로 인해 쉽게 중단됩니다. 따라서 Ad Hoc 네트워크에서 서비스 품질(QoS)을 보장하는 솔루션은 유선 네트워크에서 사용되는 기존 솔루션과 다릅니다. 본 논문에서는 Ad Hoc 네트워크를 위한 새로운 대기열 관리 방식인 Interference Drop Scheme(IDS)을 제안합니다. FIFO(선입선출), RED(Random Early Discovery)와 같은 기존 대기열 관리 방식에서는 일반적으로 대기열 길이 제한에 따라 대기열을 관리합니다. FIFO는 대기열 제한에 따라 패킷을 삭제하고, RED는 조기에 무작위 방식으로 패킷을 삭제합니다. 반면 IDS는 무선 간섭 시간에 따라 큐를 관리하는데, 이는 MAC 계층에서 경쟁이 많아질수록 증가한다. MAC 경합이 많으면 IDS는 TCP 데이터 패킷을 삭제합니다. 간섭 시간을 관찰하고 TCP 데이터 패킷을 폐기함으로써 우리의 시뮬레이션 결과는 IDS가 TCP 성능을 향상시키고 체인, 그리드 및 랜덤 토폴로지가 있는 임시 네트워크에서 UDP의 QoS 위반을 줄이는 것으로 나타났습니다. 우리의 시뮬레이션 결과는 또한 무선 간섭 시간이 다중 홉 임시 네트워크의 대기열 관리에 대한 대기열 길이 제한보다 더 나은 측정 기준임을 보여줍니다.

Abstract: Ad hoc networking uses wireless technologies to construct networks with no physical infrastructure and so are expected to provide instant networking in areas such as disaster recovery sites and inter-vehicle communication. Unlike conventional wired networks services, services in ad hoc networks are easily disrupted by the frequent changes in traffic and topology. Therefore, solutions to assure the Quality of Services (QoS) in ad hoc networks are different from the conventional ones used in wired networks. In this paper, we propose a new queue management scheme, Interference Drop Scheme (IDS) for ad hoc networks. In the conventional queue management approaches such as FIFO (First-in First-out) and RED (Random Early Detection), a queue is usually managed by a queue length limit. FIFO discards packets according to the queue limit, and RED discards packets in an early and random fashion. IDS, on the other hand, manages the queue according to wireless interference time, which increases as the number of contentions in the MAC layer increases. When there are many MAC contentions, IDS discards TCP data packets. By observing the interference time and discarding TCP data packets, our simulation results show that IDS improves TCP performance and reduces QoS violations in UDP in ad hoc networks with chain, grid, and random topologies. Our simulation results also demonstrate that wireless interference time is a better metric than queue length limit for queue management in multi-hop ad hoc networks.

AB - Ad hoc networking uses wireless technologies to construct networks with no physical infrastructure and so are expected to provide instant networking in areas such as disaster recovery sites and inter-vehicle communication. Unlike conventional wired networks services, services in ad hoc networks are easily disrupted by the frequent changes in traffic and topology. Therefore, solutions to assure the Quality of Services (QoS) in ad hoc networks are different from the conventional ones used in wired networks. In this paper, we propose a new queue management scheme, Interference Drop Scheme (IDS) for ad hoc networks. In the conventional queue management approaches such as FIFO (First-in First-out) and RED (Random Early Detection), a queue is usually managed by a queue length limit. FIFO discards packets according to the queue limit, and RED discards packets in an early and random fashion. IDS, on the other hand, manages the queue according to wireless interference time, which increases as the number of contentions in the MAC layer increases. When there are many MAC contentions, IDS discards TCP data packets. By observing the interference time and discarding TCP data packets, our simulation results show that IDS improves TCP performance and reduces QoS violations in UDP in ad hoc networks with chain, grid, and random topologies. Our simulation results also demonstrate that wireless interference time is a better metric than queue length limit for queue management in multi-hop ad hoc networks.
