Secure group consensus
Abstract
In this chapter, couple-group consensus of multiagent systems (MASs) under denial-of-service (DoS) attacks is studied. Specifically, we study couple-group consensus problems involving DoS attacks within subgroups. We derive some necessary conditions for the MAS to remain in consensus using information about the eigenvalues of the Laplacian matrix representing the network, the Laplacian of the attack modes, and the coupling strengths. Based on simulation studies and derived conditions, we deduced that the coupling strengths between and within subgroups can be adjusted after the influence of an attack for the MAS to remain in a consensus state or to renegotiate a new consensus state.
Then we discuss adaptive ...
