숨겨진 터미널 문제로 인해 충돌이 자주 발생하고 Ad Hoc 네트워크의 처리량이 크게 감소합니다. 네트워크 공간 재사용이 적으면 병렬 전송도 줄어들어 네트워크 처리량이 더욱 감소합니다. 숨겨진 터미널을 제거하고 공간 재사용을 개선하는 것은 네트워크 처리량을 향상시키는 두 가지 중요한 접근 방식입니다. 본 논문에서는 누적된 간섭과 환경 잡음을 고려하여 숨겨진 단말의 공간적 분포를 분석한다. 숨겨진 터미널의 분포는 송신기-수신기 거리, SINR 요구 사항 및 노드 밀도와 같은 여러 요소의 영향을 받기 때문에 고정된 통화중 송신 전력을 사용하는 것은 비효율적입니다. 숨겨진 터미널을 제거하고 네트워크 공간 재사용을 향상시키기 위해 EDBTMA라는 DBTMA의 향상된 기능이 제안되었습니다. 이는 적응형 통화 중음 전력 제어 방식을 사용하여 달성됩니다. 수신기는 수신된 신호 전력과 축적된 간섭에 따라 통화중 신호음의 전송 전력을 적응적으로 조정하여 모든 숨겨진 터미널(숨겨진 터미널만)이 통화중 신호음에 포함되도록 합니다. 시뮬레이션 결과는 EDBTMA 프로토콜이 DBTMA보다 숨겨진 터미널 문제를 해결하고 네트워크 공간 재사용을 개선할 수 있으며 DBTMA에 비해 65%의 추가 네트워크 처리량을 달성할 수 있음을 보여줍니다.

Abstract: The hidden terminal problem leads to frequent collisions and decreases the throughput of ad hoc networks dramatically. Low network spatial reuse also results in fewer parallel transmissions, which further leads to reduced network throughput. Eliminating the hidden terminals and improving the spatial reuse are two important approaches to improving network throughput. In this paper, spatial distribution of the hidden terminals is analyzed in consideration of accumulated interference and environmental noise. As the distribution of hidden terminals is affected by many factors such as transmitter-receiver distance, SINR requirement and nodes density, it is inefficient to use fixed busy tone transmission power. To eliminate the hidden terminals and improve network spatial reuse, an enhancement to DBTMA named EDBTMA is proposed. This is achieved by using an adaptive busy tone power control scheme. Receivers adjust the transmission power of busy tone according to received signal power and accumulated interference adaptively so that all hidden terminals (and only hidden terminals) are covered by the busy tone. Simulation results show that EDBTMA protocol can solve the hidden terminal problem and improve network spatial reuse better than DBTMA and achieves 65% additional network throughput compared to DBTMA.

AB - The hidden terminal problem leads to frequent collisions and decreases the throughput of ad hoc networks dramatically. Low network spatial reuse also results in fewer parallel transmissions, which further leads to reduced network throughput. Eliminating the hidden terminals and improving the spatial reuse are two important approaches to improving network throughput. In this paper, spatial distribution of the hidden terminals is analyzed in consideration of accumulated interference and environmental noise. As the distribution of hidden terminals is affected by many factors such as transmitter-receiver distance, SINR requirement and nodes density, it is inefficient to use fixed busy tone transmission power. To eliminate the hidden terminals and improve network spatial reuse, an enhancement to DBTMA named EDBTMA is proposed. This is achieved by using an adaptive busy tone power control scheme. Receivers adjust the transmission power of busy tone according to received signal power and accumulated interference adaptively so that all hidden terminals (and only hidden terminals) are covered by the busy tone. Simulation results show that EDBTMA protocol can solve the hidden terminal problem and improve network spatial reuse better than DBTMA and achieves 65% additional network throughput compared to DBTMA.
