A novel approach to fault tolerant multichannel networks designing problems

Abstract

This work presents solution of a bus interconnection network set designing task on the base of a hypergraph model. In order to do this the interconnection network is presented as a multipartite hypergraph. A system with virtual bus connections functioning in an environment of common physical channel was analyzed, which is characteristic of the networks based on the WDM technology. The mathematical reliability model was proposed for two modes of system functioning: with redundancy of communication subsystem and division of communication load. As solution estimation criteria the expected changes of processing efficiency changes were used as also a communication delay change criteria and system reliability criteria. The designing task solution is searched in a Pareto set composed of Pareto optima. The selection procedure of a specific solution in the case of its equivalency in relation to a vector goal function was presented.

A Heterogeneous Parallel Processing System Based on Virtual Multi-Bus Connection Network

“…Another important parameter of the computational system, especially for industrial application, is its reliability. The research used the reliability model developed by the authors assuming the equivalence of processing nodes and the interrelationship between physical and logical components of the connection network [15], [18], [22].…”

Simulation of reconfiguration problems in sensor networks using OMNeT++ software

“…Wireless sensor reliability is determined based on the Poisson distribution (1). It is defined as the probability of failure of the sensor node over the time where λ k is a coefficient of k nodes failure at the time t [2,7,4,5,6].…”

Therefore, saving energy consumption of wireless sensor network nodes is a task of great importance in the designing process [8,7,9,5,6].…”
