By Kaigui Wu, Changze Wu, Lu Liu, Jie Xu
Issue Date:May 2010
pp. 180-184
Efficient resource search in large-scale unstructured peer-to-peer (P2P) systems remains a fundamental challenge. In order to improve search performance, interest-based search is a good way to tackle the challenge. However, the existing interest-based sear...
 
A Novel Authentication Mechanism Based on CGA for BU Message Disposal in Mobile IPv6
Found in: Networking, Architecture, and Storage, International Conference on
By Yong Feng, Zhongfu Wu, Jiang Zhong, Chunxiao Ye, Kaigui Wu
Issue Date:June 2008
pp. 137-143
In mobile IPv6, the location of a mobile node (MN) is obtained by implementing a binding update (BU) process. During the process, the unauthenticated BU message may give rise to many security risks, such as denial-of-service (DoS) attack. Thus, authenticat...
 
QoS-aware service composition in multi-network environment based on genetic algorithm
Found in: Software Maintenance and Reengineering, European Conference on
By Minghui Li, Kaigui Wu, Lu Liu
Issue Date:August 2011
pp. 1231-1235
QoS-aware service composition is one of the most important technologies in SOA. The aim is to compose a new service with the best QoS under the user constraints by a set of atomic services. There are a lot of researches on this topic in recent years. But m...
 
Near-optimal configuration of service pool size in service composition
Found in: Software Maintenance and Reengineering, European Conference on
By Pan He,Kaigui Wu, Qi Xie,Jie Xu
Issue Date:August 2011
pp. 1252-1257
To improve the reliability of service composition, service pools with redundant services are often registered in advance. Increasing the number of redundant services in a pool could improve the reliability while decreasing the performance or increasing unn...
