The quotient structure defined by a specific equivalence relation allows to simplify the study of complex communications between processes in computer networks. The quotient also preserves the initial algebraic structure. This paper describes an algebraic structure modelling the communication in computer networks; it continues the study initiated in [1]. Given two communicating processes, we co...

In this paper, we proposed an algorithm to estimate the reliability of a hybrid computer communication network. A hybrid computer network is a network that consists of wire and wireless sub networks. The proposed algorithm is built upon using a simulation model due to the complexity of the network topology. We tested the proposed algorithm, and the results show consistency in the reliability es...

This paper deals with fuzzy cellular neural networks (FCNNs) with leakage delays and proportional delays. Applying the differential inequality strategy, fixed point theorem and almost periodic function principle, some sufficient criteria which ensure the existence and global attractivity of a unique almost periodic solution for fuzzy cellular neuralnetworks with leakage delays and p...

this study tries to provide a virtual image of the structure and design of facenama, cloob, facebook and google+ social networks. the main question in this study is which variable or variables are differ in the structure and design of social networks of iranian and non-iranian. content analysis has been used in this study. content analysis is a research method to describe the objective, systema...

The rapid evolution of today's computer and communication networks, that are becoming the nervous system of economical and social life, indicates the need to give greater importance to the quality management and control of these networks and of the corresponding services offered to the end-users. In order to create an SNMP-based quality management framework that a network administrator could us...

Abstract- Communication has become inevitably part of our day to day activities, in academic, business, banking, and other sectors. It has therefore become so important to implement good and efficient communication system. A reference point according to this research is the wireless sensor networking (WSN) system, and most important thing in communication is to be free from interference, attenu...

Multistage networks (MIN) are used as interconnection structure in a large number of applications. Their performance is mainly determined by their communication throughput which, in most cases, has to be investigated by time-consuming simulations or approximated by simple models. In this paper, we investigate the steady state through-put of single buuered multistage interconnection networks usi...

The Internet, as well as many other networks, has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of computer viruses. We analyze real data from computer virus infections and find the average lifetime and prevalence of viral strains on the Intern...
