Service Discovery is expected to become a crucial application of mobile ad hoc networks (MANETs). A number of existing service discovery protocols is mainly aimed at infrastructure-based and/or 1-hop ad hoc wireless networks. In this paper, we propose a novel mechanism using hierarchical grid architectures for service discovery in MANET. The geographic area of MANET is partitioned into 2D logic...

Optimal Resource management Techniques (ORMT) will provide an efficient Grid Resource allocation automatically for a user who is submitting the job without grid knowledge, design a Grid service (portal) for selects the Best Fault tolerant Resource for a given task in a fast and efficient manner, and provide an Enhanced grid balancing system for multi-tasking. Best QOS (Quality of Service) param...

As Grids are emerging as the next generation service-oriented computing platforms, they need to support Grid economy that helps in the management of supply and demand for resources and offers an economic incentive for Grid resource providers. To enable this Grid economy, a market-like Grid environment including an infrastructure that supports the publication of services and their discovery is n...

The core services in cloud computing environment are SaaS (Software as a Service), Paas (Platform as a Service) and IaaS (Infrastructure as a Service). Among these three core services server virtualization belongs to IaaS and is a service technology to reduce the server maintenance expenses. Normally, the primary purpose of sever virtualization is building and maintaining a new well functioning...

Peer-to-peer organization of Grid resource discovery services would have several desirable features, including high scalability, high reliability, self-organization and self-healing. In this paper, we describe challenges in applying P2P techniques to Grid services. These include the choice of overlay configuration and varying security requirements for Grid and P2P environments. We present the d...

This paper presents a way of searching remote procedures in OGSAbased GridRPC systems. GGF recommends a grid-enabled, remote procedure call mechanism (GridRPC) to provide a low barrier to acceptance for grid by providing a well-known and established programming model that allows the full use of grid resources while hiding the tremendous amount of infrastructure necessary to make grids work. In ...

Taking into account of the difficulties in improving utilization efficiency of the larger-scale and expensive research education resources, distributed in national universities, an education resources sharing grid based on network was investigated and developed. The grid architecture, sharing mechanism and framework that address these problems by defining a resource selection service for locati...

In grid environment, resources and services distributed with dynamic and heterogeneous characteristics. Efficient service discovery is one challenging issue in grid environment. In this paper, we propose a new distributed and hierarchical mechanism for service discovery in grid environment. This approach has five layers that in previous works presented in four layers. Root layer added as covera...
