This work focuses on a consensus problem of multi-agent systems (MASs) under an event-triggered control (ETC) subject to denial-of-service (DoS) jamming attacks. To reduce the communication cost, a novel event-triggering mechanism (ETM) is applied to determine whether the sampled signal should be transmitted or not. Unlike the periodic DoS jamming attacks strategy, the occurrence of DoS jamming attacks is irregular in this article, where attack attributes such as attack frequency and attack ratio are uncertain. Moreover, compared with some existing related results considering fixed undirected topologies, the communication topologies may change due to DoS jamming attacks in this work. In view of this, based on the piecewise Lyapunov function, sufficient conditions are derived to guarantee that the consensus problem of the MASs can be solved. Finally, the effectiveness and correctness of the theoretical results are verified by a numerical example.
