Data-centric network plays an important part in the next generation network architecture. And name system is one of basic elements in data-centric network. This paper describes an approach which achieves the name system design criterion. In naming, a combination of three entities is used to achieve security, scalability, and flexibility. In name resolution, a three-layer structure is proposed to achieve...
Resource discovery in large-scale distributed systems is a challenging issue, mainly due to the traditional centralized topologies in which the nodes of these systems are typically organized. This unified approach has been proven to be effectual for cluster-based grids and clouds but questionable for large scale, heterogeneous and dynamically interoperable e-infrastructure such as grids and inter-clouds...
In large-scale computational Grids, discovery of heterogeneous resources as a working group is crucial to achieving scalable performance. This paper presents a resource management scheme including a hierarchical cycloid overlay architecture, resource clustering and discovery algorithms for wide-area distributed Grid systems. We establish program/data locality by clustering resources based on their...
This paper presents a novel DVB/IP infrastructure that exploits P2P technology for optimised resource exploitation in interactive services' provision. Building upon a prototype DVB-T regenerative platform, it presents a decentralised architecture that exploits the broadcasting stream as part of the core/backbone network, providing interactive IP services to rural/urban citizens. Users access the provided...
Cloud computing can be widely applied to various IT systems to resolve data backup of current systems, as well as data management, system monitoring and so on for it does well in large scale data handling and distributed system management. Firstly, the architecture for information system based on cloud computing is discussed and the concept hierarchical model for cloud computing based information...
An approach based on overlay networking can lead to a novel P2P Service Platform (PSP) that Operators can fruitfully use to compete with Web Companies. The merits and the strengths of the approach are highlighted respect to the de-perimeterization of services. Critical points of overlay networking are tackled by the integration of technologies like autonomic, virtualization, cognition and negotiation...
The SORMSYS project's main goal is to optimize resource management in large scale distributed systems with the capability of self-organization. This paper will present the design of management architecture based on existing middleware solutions through the design of algorithms and methods inspired by natural models. The architecture is full decentralized and it will aim to optimize resource management...
JXTA is a P2P network using RDV (rendezvous) and DHT (Distributed Hash Table) technology. According to the student's study schedule, E-learning Resource Management & Distribution System (ERMDS) using the JXTA P2P network adopts subscription model to auto-distribute e-learning resources among the student's P2P nodes individually.
Service discovery (SD) protocols in Wireless Sensor Networks (WSNs) enable the sensor nodes to locate services offered by other nodes in the same or any other network and invoke the services. But it is a crucial task for sensors to perform timely service discovery in a pervasive environment. Also ongoing research in this field is limited with only few SD protocols proposed for some specific use cases...
To mitigate inter-cell interference (ICI) and achieve higher spectrum efficiency, fractional frequency reuse (FFR) has been widely adopted by the next generation wireless systems, wherein different frequency reuse factors are applied to cell center and cell edge zones. In such conventional FFR, a contiguous radio spectrum is partitioned in a fixed fashion across all cells for edge and cell center...
The testbed allows experimenting with highlevel distributed information fusion, dynamic resource management and configuration management given multiple constraints on the resources and their communication networks. The testbed provides general services that are useful for testing many information fusion applications. Services include a multi-layer plug-and-play architecture, and a general multi-agent...
The current Internet traffics depend more on the P2P type communication than the legacy client-server type communication. The P2P communication has been applied to diverse systems such as the VoIP and the file sharing system for the P2P potential ability. The distributed file sharing system over the P2P network using DHT (distributed hash table) can especially provide the quick search, while the file...
Based on analysis of various P2P architectures, the authors in this paper integrate semantic grid with super-peer P2P architecture. First of all, the authors introduce resources searching algorithm based on semantic cluster, and analyze the educational resources sharing mechanism & service system based on super-peer P2P, especially on the model of super-peer P2P. Then the authors focus on the...
Deployment of applications and scientific workflows that require resources from multiple distributed platforms are fuelling the federation of autonomous clouds to create cyber infrastructure environments. As the scope of federated cloud computing enlarges to ubiquitous and pervasive computing, there will be a need to assess and maintain the trustworthiness of the cloud computing entities. In this...
In this study the task scheduling problem in Grid computing environments has been addressed. To resolve the problem a set of Grid Services are defined and implemented conforming to the OGSA standards. The proposed scheduling architecture is semantically enhanced and provides the most appropriate assignment of tasks to computing resources, given the current load conditions of each computing resource...
Mobile video broadcasting service, or mobile TV, is a promising application for 3G wireless network operators. Most existing solutions for video broadcast/multicast services in 3G networks employ a single transmission rate to cover all viewers. The system-wide video quality of the cell is therefore throttled by a few viewers close to the boundary, and is far from reaching the social-optimum allowed...
Peer-to-peer (P2P) architectures are gaining increasing popularity in disseminating content to a large number of nodes. In this paper, we show that small coalitions between peers can further enhance the performance of current P2P architectures. Small coalitions bridge the gap between inefficient non-cooperative and fully cooperative architectures by establishing a robust tradeoff between the complexity...
In this paper, a access architecture for joint radio resource management (JRRM), hierarchical architecture, is given after analyzing advantage and disadvantage of the existing architectures, which is consider as one of architectures the future heterogeneous radio networks most possibly uses .Then a novel scheme is proposed based on this hierarchical architecture and the work flow of it is discussed...
The resource allocation problem is a classical problem in the scientific literature. Here, authors present an architectural model to allow optimum resource allocation in a grid environment. They are investigating a decentralized approach to address this problem into an inter--grid nodes context; instead they argue in favor of a centralized approach in an intra--grid node context (i.e., a cluster architecture)...
Large scale systems such as the Grid need scalable and efficient resource allocation mechanisms to fulfil the requirements of its participants and applications while the whole system is regulated to work efficiently. Economics inspired models have shown to efficiently allocate resources and services, scaling up well as they are decentralized. However most of existing implementations rely on a single...
