one of the key reasons for developing Grid Computing is to enable an engineer to use a high performance ‘super-computer’ with Internet network resources, resolve complexity problem. How to integrate these disparate systems resources, together under a unified framework, can be easily shared with other systems is very important. An Agent Framework for the Grid Computing is presented. Agent-based ...

We review and consider problems of Quality of Service (QoS) provisioning, resource allocation and pricing in computer networks and information systems. We consider such complex systems as economies where multiple classes of users (consumers) compete for resources and services from suppliers: network providers and information providers (servers). The resources under contention are network bandwi...

Parallel computer architectures utilize a set of computational elements (CE) to achieve performance that is not attainable on a single processor, or CE, computer. A common architecture is the cluster of otherwise independent computers communicating through a shared network. To make use of parallel computing resources, problems must be broken down into smaller units that can be solved individual...

We propose a new type of secure computer architecture that can enable computers to prevent intruders from obtaining data stored in the computer system. Based on the modified Neumann model as we proposed with a recent pending patent, the network communication component is separated from the other parts of the computer system with a separate system bus. Data exchange between the two system buses ...

Grid computing is a form of distributed computing that involves coordinating and sharing computational power, data storage and network resources across dynamic and geographically dispersed organizations.Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common goal. The resources in the Grid are heterogeneous and geographi...

ABSTRACT With the spread of the Internet, services that communicate to other services are increasing. Multimedia applications such as video on demand also ask for network Quality of Service (QoS). Thus, operating systems have to guarantee the allocation of computer resources to services. The computer resources are CPU, disk, network devices and so on. We suppose that the communications have to ...

Abstract— In order to provide complete security in a computer system and to prevent intrusion, intrusion detection systems (IDS) are required to detect if an attacker crosses the firewall, antivirus, and other security devices. Data and options to deal with it. In this paper, we are trying to provide a model for combining types of attacks on public data using combined methods of genetic algorit...

A wide range of security services may be available to applications in a heterogeneous computer network environment. Resource Management Systems (RMSs) responsible for assigning computing and network resources to tasks need to know the resource-utilization costs associated with the various network security services. In order to understand the range of security services an RMS needs to manage , a...

Accurate and reliable time is necessary for financial and legal transactions, transportation, distribution systems, and many other applications. Time synchronization protocols such as NTP (the Network Time Protocol) have kept clocks of such applications synchronized to each other for many years. Nowadays there are many commercial GPS based NTP time server products at the market but they almost ...
