With the rapid development and wide application of information technologies, computing has being transformed to a model in which services are commoditized and delivered in a manner similar to traditional utilities such as water, electricity, gas, and telephony. Compared with recently focused Cloud Computing, Market Oriented Computing still has its own peculiar applied demand and applied environment...
In recent years, the research to the Grid economy has become a hot spot with the development of Grid technology. Some models and middleware have been proposed to improve the application of Grid economy. One remarkable result of these is the Grid Architecture for Computational Economy (GRACE) which contains the functionality of resource discovery, resource trade and resource allocation. However, in...
There are much collaboration and cooperation in the dynamic, multi-institutional virtual grid. Grid provides a good bridge between the resource users and the resource providers. Especially in the agent-based grid system, agents could provide services for the scheduling of applications that make grid resources better use. We have proposed a resource discovery mechanism with negotiation in grid environment...
In recent years, the study of the grid economy is becoming a new hot spot with the grid technology development. Lots of models and middleware have been proposed by scholars to improve the application of grid economy. In our previous research work we have proposed the resource pricing fluctuation module (RPFM) as a part of grid architecture for computational economy (GRACE). However, as nodes in the...
As the key character of grid is the good service quality, the study of QoS (quality of services) becomes more and more important. And SLA (service level agreement) can really guarantee the QoS. Although SLA has been a topic in the field of telecom for many years, the researches of it in the grid are still not perfect, especially in the emerging grid economy field. In this paper, we propose a SLA control...
In traditional grid resource allocation solutions, the jobs with high-quality required may not be executed when they were allocated to low-quality offered nodes because of the separation of trust mechanism and job schedule mechanisms. Therefore, this paper combines the two mechanisms, proposes grid job schedule arithmetic driven by the expectation trust benefit. The value of the expectation trust...
Grid computing is a hot research direction in computer field. Resource management is an important part of this research. In Grid environment, satisfactory services for discovering resources and allocating appropriate resources can be provided to the Grid users though the agents. Agent based resource management with alternate solution (ABRMAS) has been proposed. But the alternate solution is not explicit...
There may be some malicious nodes in the Grid environment because the resource of nodes can access the Grid system freely. The number and qualities of this resource can be change dramatically and optionally, so it is possible to affect the utilization of Grid resource. Hence, the trust mechanism is widely used in the management of Grid. This paper proposes a new method to detect the behaviors of resource...
As the high speed development of campus network, it is necessary to build a campus data grid for sharing information. However, large quantity of data transitions may cause congestion and instable of network. In this paper, we propose a new mobile agent framework and apply mobile agent technology into campus data grid. The communication process in different parts in the new framework is detailed discussed...
The user and services provided by resources in grid environments are dynamic. Therefore, the malicious nodes may exist in grid system. It will significantly affect the quality of service (QOS) requirements of users, even lead to the economic loss of user in the grid economic environment. So a certain resource management scheme has to be implemented in grid economy environments to ensure the environments...
Grid environment is dynamic and open, therefore the reputation of entities in grid is becoming the focus of people's attention. Although, recently the study on the grid computing is resultful, the researches of reputation field are still not perfect, especially in the field of computational economy for grid. This paper presents a reputation calculation model, which is suitable in the environment of...
The research to the grid economy is gradually becomes a new hot spot with the grid technology development. In recent years there are also some remarkable results in this area of research, for example the middleware, grid architecture for computational economy (GRACE), however, in the research process, the GRACE has been discovered that the module of pricing fluctuation is not explicit. In grid economy...
