Context-Aware Quantification for VANET Security: A Markov Chain-Based Scheme

IEEE Access, 2020
Recently, the quantification of VANET security has drawn significant attention due to the lack of standard computational metrics. The salient features of VANET, such as highly dynamic connections, sensitive information sharing, and unreliable fading ...

Integration by Parts and Martingale Representation for a Markov Chain

Abstract and Applied Analysis, 2014
Integration-by-parts formulas for functions of fundamental jump processes relating to a continuous-time, finite-state Markov chain are derived using Bismut's change of measures approach to Malliavin calculus.

A Hidden Markov Model to Address Measurement Errors in Ordinal Response Scale and Non-Decreasing Process

Mathematics, 2020
A Bayesian approach was developed, tested, and applied to model ordinal response data in monotone non-decreasing processes with measurement errors. An inhomogeneous hidden Markov model with continuous state-space was considered to incorporate measurement

Modelling innovation adoption spreading in complex networks

Applied Network Science
Innovation adoption pattern has been found to be influenced by the underlying social network structure and its constituent entities. In this paper, we model innovation diffusion considering (1) the role of network structures in dictating the spread of ...

Continuous-Time Markov Chain based sequential analytical reliability assessment approach for power distribution networks

International Journal of Electrical Power & Energy Systems
Reliability assessment plays a crucial role in the planning and operation of power distribution systems. In this paper, a Continuous-Time Markov Chain with Impact-Increment State Enumeration (CTMC-IISE) method is proposed to enable sequential reliability

An Improved Delay-Dependent Stability Analysis for Markovian Jump Systems With Interval Time-Varying-Delays

IEEE Access, 2018
This paper put forward an improved stochastic stability condition for Markovian jump systems with interval time-varying delays. Markov jump parameters are modeled as a continuous-time Markov chain.

Ship Scheduling Algorithm Based on Markov-Modulated Fluid Priority Queues

Algorithms
As a key node in port logistics systems, ship anchorage is often faced with congestion caused by ship flow fluctuations, multi-priority scheduling imbalances and the poor adaptability of scheduling models to complex environments.
