Constellation resource discovery model is a novel model for discovering the dynamic resources in Grid. In constellation model, we propose a new Scalable Multi-tape Universal Turing machine (SMUTM) to present the processes of simultaneous discovery tasks on the constellation nodes, and formally describe the usability of the Grid resource based on the SMUTM. In this research, we design an algorit...

– With the rising popularity of network-based applications and the potential use of mobile ad hoc networks in civilian life, an efficient resource discovery service is needed in such networks for quickly locating resource providers. In addition, to improve user experience, QoS awareness is also crucial. In this paper, we identify the challenges when basic resource discovery techniques for the I...

Using Distributed Hash Tables (DHT) for a resource discovery in large-scale systems generates considerable maintenance overhead which affects the routing efficiency. In this paper, we propose a hierarchical DHT solution based on scalable distributed data structures (SDDS) for an efficient resource discovery in data Grids. Our solution deals with a reduced number of gateway peers running a DHT p...

Resource discovery is a fundamental problem in grid systems. Original approaches to provide grid resource discovery services are either centralized or hierarchical and proved to be inefficient when the scale of grid systems rapidly increases. A P2P network is a distributed system with the attributes of dynamicity and scalability. P2P systems have the same goal as grid systems: to share and exch...

A Grid system is essentially an infrastructure that allows location independent access to the resources and services that are provided by geographically distributed machines and networks. One of the fundamental operations needed to support location-independent computing is resource discovery. Generally, resource discovery schemes maintain and query a resource status database. Dissemination of t...

Grid Schedulers aggregate the Grid resource that belongs to multiple administrative domains in a transparent manner. The Grid resource providers have their own local resources policies for the resources that reflects the restrictions on the resource what they are providing to the users. However, the Grid users are submitting the user application along with their desired requirements for the job...

Recent advancements in technology and computing environments have extended the scope of classification criteria for traditional grids to include wireless, mobile and ad hoc grids based on the criteria of Accessibility. The realization of the benefits of grids to a larger extent is based on the effective discovery of resources (which could be heterogeneous in nature) that are part of the grid. T...

With the present ubiquitous network connections and the growing computational and storage capabilities of modern everyday-use computers, more resources, such as PCs, handheld devices (e.g., PDAs and sensors), applications, and services are on grid networks. Grid is expected to evolve from a computing and data management facility to a pervasive, world-wide resource-sharing infrastructure. To ful...

Submitted: Oct 9, 2013; Accepted: Nov 11, 2013; Published: Nov 19, 2013 Abstract: Grid computing offers an effective way to build high-performance computing systems, allowing users to efficiently access and integrate geographically distributed computers, data and applications. Grid computing and peer-to-peer computing are both hot topics at present. The convergence of the two systems is increas...

Users in ubiquitous computing environments need to find and utilize ambient resources (ubiquitous services or devices which provide ubiquitous services). In ubiquitous computing, users and resources are highly mobile, and furthermore, the attributes of ubiquitous resources may change dynamically; the static/centralized resource management systems such as conventional DNS are inappropriate for u...
