Dynamic Service Aggregation in Heterogeneous Grids

چکیده
The emergence of pervasive and mobile computing has drawn research attention to integrated mobile Grid systems. Such systems consist of a typical SOA backbone extended to include mobile and small scale devices (Personal Digital Assistants, smart-phones, multimedia devices, sensors and more). In a fully integrated model, mobile devices are able to act both as consumers and providers to open up a completely new range of very interesting possibilities in exploiting their mobile nature, unique functionality, and context awareness. However, in resource-limited environments, traditional SOA frameworks cannot easily be deployed since they assume a plethora of available device resources, and have a number of complex dependencies, thus rendering them unsuitable for resourceconstrained devices. Therefore, a smaller and simpler server-side container with reduced requirements and dependencies is needed. The contribution of this paper is two-fold: first, we present a J2ME-compliant socket-based server-side container, and second, we illustrate how an Aggregator framework enables such mobile services to be accessed using standards-based Web Services in a high-level manner.

A Scalable QoS-Aware Service Aggregation Model for Peer-to-Peer Computing Grids
Peer-to-peer (P2P) computing grids consist of peer nodes that communicate directly among themselves through wide-area networks and can act as both clients and servers. These systems have drawn much research attention since they promote Internet-scale resource and service sharing without any administration cost or centralized infrastructure support. However, aggregating different application ser...
متن کاملOnline Aggregation of Coherent Generators Based on Electrical Parameters of Synchronous Generators
This paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. An interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. Hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...
متن کاملDynamic Grid Catalog Information Service
Computational grids are heterogeneous, dynamic and distributed environments that enable large-scale sharing of resources within groups of individuals and/or institutions [9]. A grid environment collects a lot of information and information itself is a critical resource in computational grids, so it is necessary to well administrate it. A fundamental element in a grid infrastructure is the Infor...

متن کاملAn Algorithm for Distributed Aggregation-join Query Processing in Data Grids
Aggregation-join query plays an important role in query processing in data girds and has been applied to many fields, such as global climate simulation, high energy physics and molecular biology. Applying aggregation and join operations on remote relations in data grids is a unique and difficult issue due to the heterogeneous, unpredictable and volatile behaviors of the grid resources. To the b...
