Grid computing is a type of distributed computing which allows sharing of computer resources through Internet. It not only allows us to share files but also most of the software and hardware resources. An efficient resource discovery mechanism is the fundamental requirements for grid computing systems, as it supports resource management and scheduling of applications. Among various discovery me...

Peer-to-peer (P2P) networks have become an important infrastructure during the last years. Using P2P networks for distributed information systems allows us to shift the focus from centrally organized to distributed information systems where all peers can provide and have access to information. In previous papers, we have described an RDF-based P2P infrastructure called Edutella which is a speci...

The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

P2P network is factually an overlay network for distributed object store, search and sharing. This paper will present a survey about it’s recent. First, we will introduce a simple definition of P2P, and define some common operation procedures in P2P. Second, P2P performance metric will be discussed in order to understand and differentiated the practical P2P architectures and protocols. Third, t...

Overlay networks are not a new field or area of study. This domain computing will someday drive P2P systems in various application areas such as block-chain, energy trading, video multicasting, and distributed file storage. study highlights the two widely known methods routing information employed one overlay called chord. In this study, simulations both modes (iterative recursive) their variat...

P2P Grids can potentially solve large-scale scientific problems by using geographically distributed heterogeneous resources. However, a number of major technical obstacles must be overcome before this potential can be realized. One problem critical to the effective utilization of P2P Grids is the efficient scheduling of jobs. This study addresses the above-mentioned problem by describing and ev...

There is an increasing need to design and deploy multifeatured networking applications due to the fast growth of the Internet infrastructure and the use of large-scale complex applications in industries, transport, logistics, government, health, and businesses,. Important features of such applications include the capability to be self-organized, be decentralized, integrate different types of re...

Multi-agents systems communication is a technology, which provides a way for multiple interacting intelligent agents to communicate with each other and with environment. Multiple-agent systems are used to solve problems that are difficult for solving by individual agent. Multiple-agent communication technologies can be used for management and organization of computing fog and act as a global, d...

Peer-to-Peer systems have become a focus of distributed computing these years. Document discovery is a key problem in this field. In this paper, abstract indices are proposed for content-based information retrieval in Peer-to-Peer systems, especially for multimedia documents. Abstract information is extracted from the shared documents of each peer, then the similar documents on other peers can ...

We present the NanoPeers architecture paradigm, a peer-to-peer network of lightweight devices, lacking all or most of the capabilities of their computer-world counterparts. We identify the problems arising when we apply current routing and searching methods to this nano-world, and present some initial solutions, using a case study of a sensor network instance; Smart Dust. Furthermore, we propos...
