A reliability evaluation module is presented for study of WDM network reliability. In this module, WDM networks are assumed to consist of three kinds of network elements nodes, links and wavelength channelrelated elements. And a network performance index – network ‘function value’, was introduced here as a quantitative representation of working-state of WDM network under certain link capacity a...

The problem of reliability modeling on the Scalable Coherent Interface (SCI) rings and topological network is studied. The reliability models of three SCI rings are developed and the factors which influence the reliability of SCI rings are studied. By calculating the shortest path matrix and the path quantity matrix of different types SCI network topology, the communication characteristics of S...

Reliability analysis is an important issue in wireless sensor networks (WSNs). This paper aims to study the reliability of a data flow in event-driven wireless sensor networks with multiple sending transmission approach without acknowledgments. Initially, an event-driven wireless sensor network model is described in terms of limited node battery energy and shadowed fading channels. Then, in ord...

In this paper i have adopted an efficient approach for calculating the reliability of the computer communication network with the help of binary decision diagram. The computer communication network has imperfect nodes and imperfect links. It means the nodes as well as the communication links may fail with known probability. The network is represented in the form of a directed graph. First i hav...

Optimization of computer communication network based on reliability theory is problem with multiple constrained conditions. Based on the analysis of reliability theory of computer communication theory, this research discussed the multiobjective optimal model in computer communication network combining with principle of multi-objective optimal design and completed a set of analysis on network co...

Nowadays Wireless Sensor Network (WSN) is top rising field .It is broadly used in lots of application areas since previous few years. Sensor is the mainly significant and fundamental part in WSN. Reliability is one of the key aspects of WSN. Reliability is nothing but the consistency in measuring the results. It is necessary for efficient and reliable data transmission process. Congestion contr...

Network topological optimization in communication network is to find the topological layout of network links with the minimal cost under the constraint that all-terminal reliability of network is not less than a given level of system reliability. The all-terminal reliability is defined as the probability that every pair of nodes in the network can communicate with each other. The topological op...

We study the reliability of large networks of coupled neural oscillators in response to fluctuating stimuli. Reliability means that a stimulus elicits essentially identical responses upon repeated presentations. We view the problem on two scales: neuronal reliability, which concerns the repeatability of spike times of individual neurons embedded within a network, and pooled-response reliability...
