Vehicular Traffic poses an emerging issue nowadays. The critical factors for the data communication are speed and time tradeoffs. For data communication, gathering and retrieving information many cost-effective and tested techniques are required in VANET. Client server architectures being coercive are commonly used in spite of having drawbacks of fault and time in-effectiveness. This paper elab...

Fault detection and its restoration is the major challenge for smooth functioning of Multi-Level Inverter (MLI). In this paper, fault clearance scheme an Open Circuit (OC) on a 3-level 5-level Cascaded H-Bridge (CHBMLI) has been developed tested to improve reliability suitability system. An accurate fast detection, isolation bypassing faulty bridges enhance reliability, suitability, acceptabili...

Many time-critical applications require predictable performance and tasks in these applications have deadlines to be met even in the presence of faults. Three diierent approaches have evolved for fault-tolerant scheduling of real-time tasks in multiprocessor systems-Triple Modular Redundancy (TMR), Primary Backup (PB), and Imprecise Computation (IC). In TMR approach, the fault detection is by v...

Empirically based rate-and-state friction laws (RSFLs) have been proposed to model the dependence of friction forces with slip and time. The relevance of the RSFL for earthquake mechanics is that few constitutive parameters define critical conditions for fault stability (i.e., critical stiffness and frictional fault behavior). However, the RSFLs were determined from experiments conducted at sub...

We propose and analyze an FDDI-Based Reconfigumble Network (FBRN), with the aim of providing fault-tolerant real-time communication services in mission-critical systems. An FBRN consists of multiple FDDI tmnk rings and has the ability to reconfigure itself in the face of extensive damage. We discuss diflerent fault management mechanisms built into the network and analyze their impact on availab...

Recently the wavelength division multiplexing (WDM) networks are becoming prevalent for telecommunication networks. However, even a very short disruption of service caused by network faults may lead to high data loss in such networks due to the high date rates, increased wavelength numbers and density. Therefore, the network survivability is critical and has been intensively studied, where faul...

Dependability is an important requirement in hard real-time applications due to the potentially catastrophic consequences of failures. In these systems, fault tolerance mechanisms like temporal redundancy are adopted to improve reliability. Most of these types of systems are increasingly moving towards integrating critical and non-critical functionalities on the same platform to, e.g., better u...

One of the key bene ts of future hardware implementations of certain arti cial neural networks (ANN's) is their apparently \built-in" fault tolerance which makes them potential candidates for critical tasks with high reliability requirements. This paper investigates the fault-tolerance characteristics of time-continuous, recurrent ANN's that can be used to solve optimization problems. The princ...

Middleware implementation of various critical services required by large-scale and complex real-time applications on top of COTS operating system is currently an approach of growing interests. Its main goal is to enable significant reduction in the complexity of application system design and implementation by separating the concerns of the application designer for the application functionality ...
