论文摘要
在本文中,我们研究了具有数据速率限制的拒绝服务(DOS)攻击下的多项式共识问题。我们首先考虑没有领导者的共识问题,然后简要介绍对领导者的共识分析。代理的动力学采用以均匀线性时间不变系统建模的一般形式。在我们的分析中,在存在DOS攻击的情况下,我们可以根据多代理系统的数据速率获得无领导者和领导者的共识,并在此范围内获得了量化溢出的问题。该论文的主要贡献是表征无领导者和领导者共识的可容忍的DOS攻击水平与代理商之间通信尝试期间量化器的所需数据速率之间的权衡。为了减轻DOS攻击的影响,我们采用了动态量化,并具有缩放和缩放功能来避免量化饱和。
In this paper, we study multi-agent consensus problems under Denial-of-Service (DoS) attacks with data rate constraints. We first consider the leaderless consensus problem and after that we briefly present the analysis of leader-follower consensus. The dynamics of the agents take general forms modeled as homogeneous linear time-invariant systems. In our analysis, we derive lower bounds on the data rate for the multi-agent systems to achieve leaderless and leader-follower consensus in the presence of DoS attacks, under which the issue of overflow of quantizer is prevented. The main contribution of the paper is the characterization of the trade-off between the tolerable DoS attack levels for leaderless and leader-follower consensus and the required data rates for the quantizers during the communication attempts among the agents. To mitigate the influence of DoS attacks, we employ dynamic quantization with zooming-in and zooming-out capabilities for avoiding quantizer saturation.
