Abstract

This paper proposes a stochastic/dynamic routing protocol which aims the minimization of the summation of time average expected power expenditure with buffer stability in mobile ad-hoc 60 GHz wireless networks. By using 60 GHz RF, the wireless devices can transmit/receive 1080p HD video signals without compression. In addition, our algorithm works without centralized controller, so that the distributed operation is available. The novelty of the proposed algorithm was also verified by simulations.

본 논문은 60 GHz 채널을 사용하는 무선장치들이 멀티홉 애드혹 네트워킹의 형태로 배치되어 있을 때에 일부 무선 장치들에서 발생한 비디오 트래픽을 에너지 효율적이며 버퍼가 안정적인 형태로 전달하는 동적/추계적 라우팅 알고리즘을 제안한다. 제안하는 알고리즘은 모든 장치가 정보를 공유할 필요 없이 분산적으로 운영이 되기 때문에 중앙에서 알고리즘을 운영하는 제어장치가 필요 없다. 제안하는 알고리즘에 대한 성능은 시뮬레이션을 통하여 검증되었다.
