Abstract: The problem of the distributed interval estimation is studied for sensor networks under the denial-of-service (DoS) attack and the adaptive event-triggered protocol (AETP). The DoS attacks are described by the attack frequency and occurred duration in the channels between the local estimator and its neighbor nodes. Furthermore, AETP is employed to reduce the communication burden resulting from the limited bandwidth of communication networks. The dynamic threshold parameters of the proposed AETP are governed by an adaptive law, which is directly related with the error between the innovation at the current instant and the broadcast innovation at the latest trigger instant. The purpose of this article is to design a distributed interval estimator by utilizing the local information and the neighboring information such that, in the simultaneous presence of AETP, the bounded noises, and the aperiodic DoS attacks, system real states are involved in an interval. Then, some sufficient conditions are gained by employing the stability analysis theory and positive system theory, and the desired estimator gains are obtained by solving a set of linear matrix inequalities. Finally, a simulation example is proposed to show the effectiveness of the developed method.
