Although some existing collaborative intrusion detection schemes can increase the
detection performance by dynamically allocating detection resources in smart grids, these
related works fail to consider the optimization of resource allocation between IDSs under the
condition of resource restriction. In this paper, considering the effect of resource restriction,
we propose a resource allocation scheme for two-layer collaborative IDSs based on sharing
strategies in smart grids. In the first layer of our scheme, we model the interaction between …
