Construction and Arena Simulation of Grid M-Commerce Process

Grid Technology

“Grid” is a new technique building on the Internet, which blends high speed Internet, high performance computers, large databases, sensors, and remote equipments as a whole, providing more resources, function and interactivity for technicians and ordinary people. Grid technologies form a super computer that integrates all resources from different physical locations in Internet, realizing the widely sharing of information and resources.

Mobile grid is the extending of traditional grid in the wireless circumstance. It supports mobile users and resources seamlessly, transparently, safely and effectively. The mobile grid (Figure 1) integrates mobile devices, consisting of a resources sharing network with mobile notes.

Grid Management

Grid management emerges from grid computing that can realize information integration, synergic operation and information sharing (Shen, 2006). This idea divides objects into grid units according to certain principles, and makes the units communicate with each other effectively, sharing the resources apparently with the help of IT and coordinate mechanism to improve the management efficiency.

Grid management has several features, including: (1) slices combining with pieces; (2) operation process reengineering; (3) supreme customers; (4) resources sharing; and (5) systematic supervision and administration (Zheng, Xu & Wang, 2005).

The process of grid management is abstracted as follows (Yuan, Wang & Ma, 2007):

• 1.

  Business Acceptance. Accept all demand applications from clients at the same platform, and verify the demands.

• 2.

  Business Dispatch. Recognize and subdivide the type of demands, dispatching tasks to the corresponding functional department.

• 3.

  Business Conduction. Functional departments accept tasks, dealing their tasks according to the specific requirements.

• 4.

  Service Delivery. Task execution information feeds back to the users or acceptance center, which reflects the publicity of information in grid management.

• 5.

  Supervision and Inspection. Users confirm and evaluate received services, and supervision departments supervise the business process and node participants.
