Interactivity-Constrained Server Provisioning in Large-Scale Distributed Virtual Environments
Found in: IEEE Transactions on Parallel and Distributed Systems
By Duong Nguyen Binh Ta, Thang Nguyen, Suiping Zhou, Xueyan Tang, Wentong Cai,R. Ayani
Issue Date:February 2012
pp. 304-312
Maintaining interactivity is one of the key challenges in distributed virtual environments (DVEs). In this paper, we consider a new problem, termed the interactivity-constrained server provisioning problem, whose goal is to minimize the number of distribut...
 
Clustering with Multiviewpoint-Based Similarity Measure
Found in: IEEE Transactions on Knowledge and Data Engineering
By Duc Thang Nguyen, Lihui Chen, Chee Keong Chan
Issue Date:June 2012
pp. 988-1001
All clustering methods have to assume some cluster relationship among the data objects that they are applied on. Similarity between a pair of objects can be defined either explicitly or implicitly. In this paper, we introduce a novel multiviewpoint-based s...

Interactivity is a key consideration in large-scale distributed virtual environments (DVEs), such as massively multi-player online games. Due to the Internet dynamics as well as the large-scale and distributed nature of many DVEs, it is difficult to quanti...
 
On Solving Distributed Fuzzy Constraint Satisfaction Problems with Agents
Found in: Intelligent Agent Technology, IEEE / WIC / ACM International Conference on
By Xuan Thang Nguyen, Ryszard Kowalczyk
Issue Date:November 2007
pp. 387-390
Fuzzy Constraint Satisfaction Problem (FCSP) offers flexible modelling and solving of many real world problems such as scheduling and resource allocation. In this paper, we focus on Distributed Fuzzy Constraint Satisfaction problems (DisFCSP) where fuzzy c...
 
A Graph-Based Multi-Agent Planning Algorithm with QoS Guarantees
Found in: Intelligent Agent Technology, IEEE / WIC / ACM International Conference on
By Jian Feng Zhang, Xuan Thang Nguyen, Ryszard Kowalczyk
Issue Date:November 2007
pp. 273-276
Many existing planning approaches assume the existence of a centralized planner that has complete information of its planning problem. However, with the increasing popularity of distributed paradigm today, a planning problem may span across the boundaries ...
 
An Agent Based QoS Conflict Mediation Framework for Web Services Compositions
Found in: Intelligent Agent Technology, IEEE / WIC / ACM International Conference on
By Xuan Thang Nguyen, Ryszard Kowalczyk
Issue Date:December 2006
pp. 522-528
Web services technology is prevailing for business-to- business integration due to its well defined infrastructure enabling interoperability among heterogeneous applications. However, this interoperability promise also poses a difficulty in building a Web ...
 
Dynamic Asynchronous Aggregate Search for Solving QoS Compositions of Web Services
Found in: Web Intelligence and Intelligent Agent Technology, International Conference on
By Xuan Thang Nguyen, Ryszard Kowalczyk, Khoi Anh Phan
Issue Date:December 2006
pp. 142-145
There has been recently an increase of interests in Distributed Constraint Satisfaction (DisCSP) algorithms. Most of these algorithms assume that the set of variables and constraints in a DisCSP are completely known and fixed. However, these assumptions do...
