Quality of service (QoS) is a major concern in the design and management of a composite service. In this paper, a systematic approach is proposed to calculate QoS for composite services with complex structures, taking into consideration of the probability ...
 
Bootstrapping Trust and Reputation for Web Services
Found in: 2012 IEEE 14th International Conference on Commerce and Enterprise Computing (CEC)
By Hien Trang Nguyen,Jian Yang,Weiliang Zhao
Issue Date:September 2012
pp. 41-48
Trust and reputation of web services is usually established based on the historical information about past transactions or rating scores collected over a period of time. However, when a new web service joins a community, normally there is not much informat...

QoSDIST: A QoS Probability Distribution Estimation Tool for Web Service Compositions
Found in: Asia-Pacific Conference on Services Computing. 2006 IEEE
By Huiyuan Zheng, Jian Yang, Weiliang Zhao
Issue Date:December 2010
pp. 131-138
In this paper, a QoS Distribution estimation Tool (QoSDIST) is developed to estimate the QoS distributions for service compositions. QoSDIST can generate QoS probability distributions for component web services. When estimating the QoS probability distribu...
 
Managing Changes for Service Based Business Processes
Found in: Asia-Pacific Conference on Services Computing. 2006 IEEE
By Yi Wang, Jian Yang, Weiliang Zhao
Issue Date:December 2010
pp. 75-82
In this paper, we propose an approach to deal with the change management for service oriented business processes. Beyond existing work, the proposed approach highlights the dependencies between services and business processes. A service oriented business p...
 
Provisioning Web Services from Resource Constrained Mobile Devices
Found in: Cloud Computing, IEEE International Conference on
By Mahbub Hassan, Weiliang Zhao, Jian Yang
Issue Date:July 2010
pp. 490-497
The increasing processing power, storage and support of multiple network interfaces are promising the mobile devices to host services and participate in service discovery network. A few efforts have been taken to facilitate provisioning mobile Web services...
 
A Trust and Reputation Model Based on Bayesian Network for Web Services
Found in: Web Services, IEEE International Conference on
By Hien Trang Nguyen, Weiliang Zhao, Jian Yang
Issue Date:July 2010
pp. 251-258
Trust and reputation for web services emerges as an important research issue in web service selection. Current web service trust models either do not integrate different important sources of trust (subjective and objective for example), or do not focus on ...
 
QoS Analysis and Service Selection for Composite Services
Found in: Services Computing, IEEE International Conference on
By Huiyuan Zheng, Jian Yang, Weiliang Zhao
Issue Date:July 2010
pp. 122-129
A composite service can be constructed with the arbitrary combination of sequential, parallel, loop, and conditional structures. In this paper, we propose a general solution to calculate the QoS for composite services with complex structures. We also show ...
 
SOAC: A Conceptual Model for Managing Service-Oriented Authorization
Found in: Services Computing, IEEE International Conference on
By Haiyang Sun, Weiliang Zhao, Jian Yang
Issue Date:July 2010
pp. 546-553
A web service can be composed of multiple component web services in a loosely-coupled environment. Traditional Role Based Access Control (RBAC) is inadequate for the authorization management of composite services since the administration of the component w...
 
A Fast Handover Scheme in IEEE802.16 Relay Networks
Found in: Future Networks, International Conference on
By Li Yun, Wang Ying, Weiliang Zhao, Xiaohu You
Issue Date:January 2010
pp. 243-247
In wireless IEEE802.16-based relay networks, link layer handover requires more signaling interactions, and the signaling cost and processing delay will increase while using MIPv6 to relay networks. Aiming to this problem, we propose a fast handover scheme ...
 
QoS Analysis for Web Service Composition
Found in: Services Computing, IEEE International Conference on
By Huiyuan Zheng, Weiliang Zhao, Jian Yang, Athman Bouguettaya
Issue Date:September 2009
pp. 235-242
The quality of service (QoS) is a major concern in the design and management of Web service composition. Existing methods for QoS calculation either do not take the probability of path execution into consideration when QoSs are provided for different execu...
 
Trust Management for Web Services
Found in: Web Services, IEEE International Conference on
By Weiliang Zhao, Vijay Varadharajan
Issue Date:September 2008
