How to safely or reliably flood a packet via broadcast scheme to all nodes in computer networks is an important issue. However, it is a big challenge and critical problem to broadcast data packets over mobile ad hoc networks reliably due to the unsettled wireless links, high mobility, and the lack of the acknowledgment (ACK) scheme. Many solutions deal with this problem by adopting multiple uni...

The behavior and nature of attacks and threats to computer network systems have been evolving rapidly with the advances in computer security technology. At the same time however, computer criminals and other malicious elements find ways and methods to thwart such protective measures and find techniques of penetrating such secure systems. Therefore adaptability, or the ability to learn and react...

This study describes the network design solution to the problem of connecting heterogeneous computer systems based on analysis of multipartite hypergraphs. To do this proposes a mathematical model of reliability for the two modes of operation of the system: with redundancy communication subsystem and the division of communication load. As the evaluation criteria applied solutions expected chang...

For example, in an s-t reliability network evaluation, the connectivity of the network requires to use a depth-first procedure as EF [2,3]. In other cases (telecommunication networks as well as pipeline systems, computer nets, transporting systems among others) the connectivity is not a sufficient condition for an operating state and the success of the network implies that a required flow is gu...

The modern computer and network system, is composed of tens of thousands of components. Any faults in components can affect reliability of the whole system. In the process of running, elements will gradually age and failure rate gradually increase. However, the rate at which these elements age is not synchronous. Thus, in which cases should the elements be upgraded or replaced and in which case...

Orifice flow meter is one of the most common devices in industry which is used for measuring the gas flow. This system includes an orifice plate, temperature and pressure transmitters, and a flow computer. The flow computer is used for collecting information related to temperature, pressure, and their differences under various conditions. Also the flow computer can calculate the flow rate of ga...
