Diagnosability of discrete-event systems
TLDR
The approach to failure diagnosis presented in this paper is applicable to systems that fall naturally in the class of DES's; moreover, for the purpose of diagnosis, most continuous variable dynamic systems can be viewed as DES's at a higher level of abstraction.
Failure diagnosis using discrete event models
TLDR
A discrete event systems (DES) approach to the failure diagnosis problem is proposed and the notion of diagnosability is discussed, and the construction procedure of the diagnoser is presented.
Vehicle-to-vehicle safety messaging in DSRC
TLDR
The results show the approach proposed is feasible for vehicle safety messages in DSRC and is compatible with the Dedicated Short Range Communications (DSRC) multi-channel architecture.
An H/sub /spl infin// approach to networked control
TLDR
A stochastic packet-loss model for the network is used and results for discrete-time linear systems with Markovian jumping parameters can be applied to study the effect of communication losses on vehicle control.
WTRP - wireless token ring protocol
TLDR
WTRP is a distributed protocol that supports many topologies, as not all stations need to be connected to each other or to a central station, and it is robust against single node failures, and recovers gracefully from multiple simultaneous faults.
Geographical routing using partial information for wireless ad hoc networks
TLDR
An algorithm for routing in wireless and ad hoc networks using information regarding the geographic location of the nodes using a new type of distributed, adaptive and asynchronous algorithm, known as a geographical routing algorithm (GRA).
Adaptive intervehicle communication control for cooperative safety systems
TLDR
Simulation results confirm that if packet generation rate and associated transmission power for safety messages are adjusted in an on-demand and adaptive fashion, robust tracking is possible under various traffic conditions.
Medium Access Control Protocol Design for Vehicle–Vehicle Safety Messages
TLDR
A Quality-of-Service (QoS) model for safety messages that are consistent with the active vehicle safety systems literature is developed and shows that under certain assumptions on the loss probability tolerated by safety applications, the design is able to transport safety messages in vehicular ad hoc networks.
Analysis of Information Dissemination in Vehicular Ad-Hoc Networks With Application to Cooperative Vehicle Safety Systems
TLDR
Following a thorough analysis of the hidden node affected VANET, it is shown that channel occupancy or busy ratio can be used as a feedback measure that quantifies the success of information dissemination and, consequently, the CVSS, under different network conditions.
A bounded real lemma for jump systems
TLDR
It is shown that the linear matrix inequality in the bounded real lemma is both necessary and sufficient for this class of systems and reduces to the standard necessary andsufficient condition for discrete-time systems.
