Abstract

This paper consider a code-division multiple-access(CDMA) wireless ad-hoc network in low-SINR regime. In previous research [6], there has been proposed a algorithm for achieving global optimum at high SINR regime, but has not been fully investigated at low-SINR regime. In this paper, we focus on a case where SINR is much smaller than 1, and propose a algorithm that is suitable for low-SINR regime.

본 논문에서는 코드분할 다중화방식(CDMA)을 기반으로 한 무선 애드혹 네트워크에서의 혼잡 제어와 전송 파워 제어의 복합 최적화 기법에 대해서 고찰하고, 낮은 신호대비 잡음 및 간섭(이하 SINR) 상황을 고려한 알고리즘을 제시한다. 기존의 연구 [6]에서 제시된 CDMA기반의 무선 애드혹 네트워크를 위한 복합 제어 방식은 높은 SINR 상황을 가정하고 있으며, 낮은 SINR 상황에 대해서는 고려하지 않았다. 본 논문에서 우리는 SINR이 1보다 상대적으로 훨씬 작은 낮은 SINR 상황에 대해서 고려해야 할 문제점들을 살펴보고, 적절한 알고리즘을 제시한다.
