Several algorithms have been developed to solve the reliability problem for nonseries-parallel networks using the sum of disjoint products (SDP) approach. This paper provides a general framework for most of these techniques. It reviews methods that help improve computer time and memory requirements in reliability computation. These parameters are generally used to compare SDP algorithms. We als...

Topological optimization of computer networks is concerned with the design of a network by selecting a subset of the available set of links such that the fault tolerance and reliability aspects are maximized while a cost constraint is met. A number of enumeration-based techniques were proposed to solve this problem. They are based on enumerating all the possible paths (for reliability) and all ...

Cyber attacks on computer and network systems induce system quality and reliability problems, and present a significant threat to the computer and network systems that we are heavily dependent on. Cyber attack detection involves monitoring system data and detecting the attack-induced quality and reliability problems of computer and network systems caused by cyber attacks. Usually there are ongo...

The reliability of distributed systems and computer networks have been modeled by a probabilistic network or a graph G. Computing the residual connectedness reliability (RCR), denoted by R(G), under the node fault model is very useful, but is an NP−hard problem. Since it may need exponential time of the network size to compute the exact value of R(G), it is important to calculate its tight appr...

This paper presents a virtual lab of connected vehicle technology. The virtual lab features an interactive website where remote users, who are unable to learn connected vehicle technology at expensive real labs, can interact with the virtual environment. A team of traffic engineers, computer scientists/engineers, and electrical engineers propose this integrated and high-fidelity simulation plat...

We use a mathematical model of an open queueing network in heavy traffic. The law of the iterated logarithm for the extreme virtual waiting time of a customer in heavy traffic in open queueing networks has been presented. Finally, we present an application of the theorem a reliability model from computer network practice. Key–Words: mathematical models of technical systems, performance evaluati...

Computer Networking is necessary to human beings. Peoples needed to share ideas, research knowledge, and the way of life to their friends. In the modern time, the role of computer networks became dreamy. Analyzing, accessing, sharing and storing of data and information are very easy with help of distributing computer networking. Social networking sites look after human communication in a better...

Inter-connecting processors and linking them efficiently to the memory modules in a parallel computer is not an easy task. Hence, an interconnection network that provides the desired connectivity and performance at minimum cost is required. The design of a suitable interconnection network for inter-processor communication is one of the key issues of the system performance. The reliability of th...

BACKGROUND Increasing application and use of information systems and mobile technologies in the healthcare industry require increasing nurse competency in computer use. Computer literacy is defined as basic computer skills, whereas computer competency is defined as the computer skills necessary to accomplish job tasks. Inadequate attention has been paid to computer literacy and computer compete...

Faults in computer networks may result in millions of dollars in cost. Faults in a network need to be localized and repaired to keep the health of the network. Fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. In this paper, we propose a novel approach based on imperialist competitive alg...
