Abstract

This paper proposes an adaptive modulation based incremental hop selection scheme which improves network coverage in half-duplex multi-hop networks. The proposed scheme guarantees wide coverage through the operation of multi-hop network while preventing spectral efficiency loss due to the usage of multiple time phases in the half-duplex protocol. Also, we evaluate the average spectral efficiency performance over Nakagami-m fading channel. The simulation results show that the proposed scheme outperforms the existing schemes and the derived evaluation is valid.

본 논문에서는 반이중 다중 홉 네트워크에서 스펙트럼 효율성 성능을 향상시킬 수 있는 적응 변조 기반의 증분형 홉 선택 기법을 제안하고 성능을 분석한다. 제안 하는 기법은 다중 홉 네트워크에서 동작하므로 넓은 네트워크 커버리지를 보장하면서도 반이중 방식에 따른 추가 시간 슬롯 사용의 빈도를 낮추어서 스펙트럼 효율성 손실을 막아준다. 우리는 본 논문에서는 제안하는 기법의 평균 스펙트럼 효율성 성능을 나카가미-m 채널에서 분석하였다. 모의실험 결과는 제안하는 기법의 우수성과 분석 된 성능의 정확함을 보여준다.
