Though research on the Grid Services has progressed at a steady pace, its promise has yet to be realized. One major difficulty is that, by its very nature, the Grid Service is a large, uncensored system to which anyone may contribute. This raises the question of how much credence to give each source. The concept and definition of trustworthy of Grid Service is given. Estimating trustworthy of G...

in wireless sensor networks (wsns), localization algorithms could be range-based or range-free. the approximate point in triangle (apit) is a range-free approach. we propose modification of the apit algorithm and refer as modified-apit. we select suitable triangles with appropriate distance between anchors to reduce pit test errors (edge effect and non-uniform placement of neighbours) in apit a...

Bayesian network has been a successful tool in the decision support systems. In the changing world, the decision making demands adaptive Bayesian methods that are composed of Bayesian inferential and learning approaches. To achieve this goal, we propose a kind of grid-enabled Bayesian networks that intend to gridify Bayesian inferential and learning methods when the advanced grid computing tech...

The advent of network innovations in optical networks has a significant influence on computational infrastructures in research projects. Grid applications and middleware, not yet aware of underlying network and its services, have been recently equipped with powerful tools and plug-ins to control and manage not only the computational, but also network infrastructures. However, at this point of t...

Since the introduction of the smart grid, accelerated deployment of various smart grid technologies and applications have been experienced. This allows the traditional power grid to become more reliable, resilient, and efficient. Despite such a widespread deployment , it is still not clear which communication technology solutions are the best fit to support grid applications. This is because di...

Network links, as the communication media for Grid transmissions, should be considered as a parameter to decide about the convenience of using other different resources, such as CPU. This is achieved by means of a scheduling algorithm, which decides which computing resource will execute each users’ jobs. This task (the scheduling of jobs to computing resources) is done by taking into account th...

The Wireless Sensor Network is a widely used approach mainly used for real time applications. Real time applications raise various fundamental problems like limited energy resources. We propose a paper on Hybrid approach which is the combination of Grid based approach and Cluster based approach. the main task of a sensor network is to minimize the energy consumption of wireless sensor network. ...

According to development of communications and web-based technologies in recent years, e-Learning has became very important for everyone and is seen as one of most dynamic teaching methods. Grid computing is a pattern for increasing of computing power and storage capacity of a system and is based on hardware and software resources in a network with common purpose. In this article we study grid ...
