One of the main challenges in Grid systems is designing an adaptive, scalable, and model-independent method for job scheduling to achieve a desirable degree of load balancing and system efficiency. Centralized job scheduling methods have some drawbacks, such as single point of failure and lack of scalability. Moreover, decentralized methods require a coordination mechanism with limited communications...
Resource discovery is critical to the usability and accessibility of grid computing systems. Distributed hash table (DHT) has been applied to grid systems as a distributed mechanism for providing scalable range-query and multiattribute resource discovery. Multi-DHT-based approaches depend on multiple DHT networks with each network responsible for a single attribute. Single-DHT-based approaches keep...
In order to solve the shortcomings of traditional resource discovery mechanism. Many sophisticated strategies are implemented to ensure that the grid resource discovery service has good scalability and efficiency. Nodes are divided into different domains, and we use improved distributed hash table technology to achieve higher local routing efficiency; the combination of the tree overlay network and...
In order to manage search-, and routing-functionality in structured P2P-networks, a lot of algorithms like CAN, Chord, Tapestry, Pastry, and more have been developed. In this paper we introduce a distributed algorithm which uses a set of simple rules to build and maintain a complete, parallel-growing and although contradiction-free grid-structure just by the use of local knowledge of each node. This...
Grid is an environment of seamless and integrated sharing and collaboration. The heterogeneous, dynamic, various and autonomous characteristics of resources make grid resource discovery a challenging issue. Hierarchical grid computing environment (hierarchical grid for short) with many advantages is far and wide used. This paper introduces small-world cluster into hierarchical grid in which intra-cluster...
We describe and evaluate a set of protocols that implement a distributed, decentralized desktop grid. Incoming jobs are matched with system nodes through proximity in an N-dimensional resource space. This work improves on prior work by (1) efficiently accommodating node and job characterizations that include both continuous and categorical resource types, and (2) scaling gracefully to large system...
In optical grid networks, the main challenge is to account for not only network parameters, but also for resource availability. Anycast routing has previously been proposed as an effective solution to provide job scheduling services in optical grids, offering a generic interface to access grid resources and services. The main weakness of this approach is its limited scalability, especially in a multi-domain...
Most research results of location services have been focused on nodes whose motions follow patterns of random waypoints. For inter-vehicular communications that happen in metropolitan areas, moving cars obviously travel on restricted directions along streets and make frequent stops over intersections. In this paper, we present intersection location service (ILS), a distributed hashing-based location...
Grid system has facilitated large scale, flexible, distributed, secure and coordinated resource sharing. It aims to make full use of the network resources and build a harmonious collaborative community. However, resource management and quick resource location are still urgent problems for grid systems, especially under large, dynamic environment. This paper presents SIKA a grid-based overlay network...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
