Abstract

We propose new routing scheme, Cooperative Diversity-based Routing (CDR) which utilizes the cooperative space diversity for power saving and performance enhancement of wireless ad-hoc networks. The improved performance is compared with Multi-hop Relay Routing (NRR) by analytical methods. When the required outage probability is $1\times10^{-3}$ at the destination node in ad-hoc networks with 7 nodes, we noticed that each node can save power consumption by 15.5 dB in average, by using our proposed CDR compared to MRR.

본 논문에서는 무선 애드혹 네트워크에서 전력 절약과 성능 개선을 위하여 협동 공간 다이버시티를 이용한 새로운 협동다이버시티 라우팅 방식을 제안한다. 제안한 방식은 기존에 사용되어온 방식인 다중 릴레이 라우팅 방법과 해석적인 방법으로 성능의 우수성을 비교하였다. 7개의 노드를 갖는 애드혹 네트워크에서 최종 노드에서 요구되는 오수신율이 $1\times10^{-3}$일 때, 제안한 협동다이버시티 라우팅 방식은 다중 릴레이 라우팅방식과 비교하여 노드당 평균 15.5 dB 전력을 절약할 수 있었다.
