摘要

针对随机信道环境下的自组织无线网络,提出了一种新的分布式功率和准入控制算法。该领域以前的工作主要集中在具有固定信道的ad-hoc网络的分布式控制上。我们表明,由这种公式产生的算法不能准确地捕捉时变信道的动态。因此,为固定信道设计的算法在随机信道中可能表现很差。为了解决这些问题,本工作提出了基于随机近似的新算法,用于随机通道中的最优分布式功率和准入控制

Distributed power and admission control for time-varying wireless networks
This paper presents new distributed power and admission control algorithms for ad-hoc wireless networks in random channel environments. Previous work in this area has focused on distributed control for ad-hoc networks with fixed channels. We show that the algorithms resulting from such formulations do not accurately capture the dynamics of a time-varying channel. Hence, algorithms designed for fixed channels may perform quite poorly in random channels. In order to address these issues, this work proposes new algorithms, based on stochastic approximation, for optimal distributed power and admission control in random channels
