CSMA/CA 기반 MAC 프로토콜은 특정 임계값 이상의 반송파 신호를 감지하면 노출된 스테이션으로부터의 패킷 전송을 보류합니다. 이는 다른 수신 스테이션과의 충돌을 피하기 위한 것입니다. 그러나 이러한 보수적인 방식은 종종 불필요하게 많은 스테이션을 노출하므로 공간 스펙트럼 리소스의 활용이 최소화됩니다. 본 논문에서는 활성 수신기의 상태를 원격으로 추정하는 것이 반송파 감지보다 무선 네트워크에서 충돌을 피하는 데 더 효과적이라는 것을 보여줍니다. 우리는 간섭 범위의 새로운 개념을 적용합니다. n- 간섭 허용 범위, 존재 시 안정적인 통신 보장 n (n≥ 0) 범위 외부에서 동시 전송. 우리는 분산형을 디자인합니다. 간섭 방지 MAC( IP-MAC )을 사용하는 n- 활성 통신을 위해 비간섭 스테이션으로부터 병렬 액세스를 가능하게 하는 허용 간섭 범위. IP-MAC에서 노출된 스테이션은 IPC(간섭 가능성 검사)를 거쳐 잠재적으로 활성 통신을 방해하는지 또는 방해하지 않는지를 확인합니다. 해결 작업 중에 IPC는 활성 수신기에서 캡처 효과를 해당 수신기 근처에서 가능한 여러 동시 전송의 간섭 신호를 고려합니다. IP-MAC이 제공하는 성능 향상은 다양한 환경에서의 시뮬레이션을 통해 연구됩니다. 결과에 따르면 IP-MAC는 처리량 및 지연 측면에서 네트워크 성능을 크게 향상시키는 것으로 나타났습니다.

Abstract: The CSMA/CA driven MAC protocols withhold packet transmissions from exposed stations when they detect carrier signal above a certain threshold. This is to avoid collisions at other receiving stations. However, this conservative scheme often exposes many stations unnecessarily, and thus minimizes the utilization of the spatial spectral resource. In this paper, we demonstrate that remote estimation of the status at the active receivers is more effective at avoiding collisions in wireless networks than the carrier sensing. We apply a new concept of the interference range, named as n-tolerant interference range, to guarantee reliable communications in the presence of n (n≥ 0) concurrent transmissions from outside the range. We design a distributed interference preventive MAC ( IP-MAC ) using the n-tolerant interference range that enables parallel accesses from the noninterfering stations for an active communication. In IP-MAC, an exposed station goes through an Interference Potentiality Check (IPC) to resolve whether it is potentially interfering or noninterfering to the active communication. During the resolve operation, IPC takes the capture effect at an active receiver into account with interfering signals from a number of possible concurrent transmissions near that receiver. The performance enhancement offered by IP-MAC is studied via simulations in different environments. Results reveal that IP-MAC significantly improves network performance in terms of throughput and delay.
