Service Grid For Business Computing, Zongwei Luo, Jia Zhang, Rosa Badia
Jia Zhang
In this chapter, we will introduce an advanced topic of grid computing – Web services-oriented grid for business computing. Web services represent a new concept of computing that enables diverse and distributed resources to communicate with each other based upon a set of standards. We will discuss what values the marriage of Web services and grid computing can bring to business computing and the current state of the art of the field. The layout of the chapter is as follows: Grid computing overview; Web services orientation; Service oriented grid; Integrated service platform for integration; and Challenges and considerations.

This case study describes the privacy issues of applying Radio Frequency Identification (RFID) in the retail industry. With the dramatic price drop of RFID tags, it is possible that RFID be applied to individual items sold by a retailer. However, the RFID technology poses critical privacy challenges. In this study, we analyze the potential privacy issue of RFID utilization, and we propose a privacy authorization model aiming for precisely defining RFID privacy policies for the retail industry.

Auction-Based Pricing Model For Web Service Providers, Jia Zhang, Ning Zhang, Liang-Jie Zhang

Applying auctions to Web services selection and invocation calls for examination due to the unique features of Web services, such as interoperable machine-to-machine interactions and reenterable bargaining services. In this paper we propose a formal model for Web services-based auctions. Examining one-sided sealed auction type, we prove mathematically that service requestors’ risk preferences could lead to different pricing strategies for service providers towards higher profit. We argue that Service Level Agreement (SLA) documents can be used to analyze service requestors’ preferences. On top of WS-Agreement, we propose a basic service requestor risk preference elicitation algorithm, as well as a historical …

A Mobile Agents-Based Approach To Test The Reliability Of Web Services, Jia Zhang
Jia Zhang
The paradigm of web services has been transforming the internet from a repository of data into a repository of services, or so-called web services. As more and more web services are published on the internet, how to opt for an appropriate and trustworthy web service poses a big challenge. In this paper we propose a mobile agents-based approach that selects reliable web service components in a cost-effective manner.
