In this article, the problem of model-based dynamic event-triggered control (ETC) cyber-physical systems (CPSs) with quantization effects and denial-of-service (DoS) attacks is studied. With aid a technique combining CPSs ETC scheme, number transmissions significantly reduced to save scarce network resources. An average dwell-time (ADT) automaton time-ratio monitor are firstly introduced describe frequency duration DoS attacks, then unified hybrid framework quantizer established. presence...

remote state estimation for an arbitrary tree topology in cyber-physical systems (CPSs) subject to Denial-of-Service (DoS) attacks. A sensor transmits its local the root node of tree, and optimal child nodes until leaf are reached. In meanwhile, a malicious attacker can jam all communication channels strategically connected attacked node. With energy constraints mind, both defender adopt strategies that involve allocating determine which protect or attack at each time step. Bayesian...

This paper investigates the problem of optimizing transmission schedule between a sensor and relay in cyber-physical systems to achieve accurate remote state estimation. The considered system model represents plant as linear time-invariant system, wherein measurements are transmitted estimator using an intelligent relay. Both nodes capable harvesting energy from external environment, they required make decisions at each time step ensure stability system's operation. In addition, sharing...

The ability to find tables and extract information from them is a necessary component of data mining, question answering, other retrieval tasks. Documents often contain in order communicate densely packed, multi-dimensional information. Tables do this by employing layout patterns efficiently indicate fields records two-dimensional form.Their rich combination formatting content present difficulties for traditional language modeling techniques, however. This paper presents the use conditional...

Cyber–physical systems (CPSs), which combine computer science, control systems, and physical elements, have become essential in modern industrial societal contexts. However, their extensive integration presents increasing security challenges, particularly due to recurring cyber attacks. Therefore, it is crucial explore CPS control.

This article considers remote state estimation in cyber-physical systems (CPSs) with multiple sensors. Each plant is modeled by a discrete-time stochastic linear system measurements of each sensor transmitted to the corresponding estimator over shared communication network when their securities are interdependent due network-induced risks. A dynamic nonzero-sum game asymmetric information formulated which subject resource budget constraint needs decide whether invest security for sending...

In this paper, an event-based physical watermark is proposed and analyzed. It well known that adding watermarks into Cyber-Physical Systems (CPSs) effective way to combat malicious attacks. However, the classical ways are based on time, which leads great decreases in Linear Quadratic Gaussian (LQG) performances while increasing detection rates. To deal with performance loss after watermarks, designed detect replay A stochastic event scheduler innovation sequence constructed indicate or not....

This paper concentrates on the optimal denial-of-service (DoS) attack power allocation strategy for remote state estimation in cyber-physical systems with two-hop networks. An intelligent relay assumption that it can conduct some simple recursive algorithms aims at transmitting system process across a vulnerable communication channel to estimator, referred as cooperative sensor. In meantime, malicious attacker disrupts transmission strategically deteriorate performance of system, but do this...

Complex (or Composite) event processing systems have become more popular in a number of areas.Non-deterministic finite automata (NFA) are frequently used to evaluate CEP queries.However, it is complex or difficult use the traditional NFA-based method process patterns with conjunction and negation.In this paper, we proposed new system LogCEP using pushdown automaton support efficient negation.First, semantic query language specification presented.Then, an named LogPDA for system.LogPDA...
