Hakima Mellah and Salima Hassas and Habiba Drias

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 1-6

Abstract: In this work we are interested in apprehending information complexity that is issued from interacting information sources, existing within an organization. We propose a model of representation according to a threedimensional view which dimensions are the content, use and structure. This allows reflecting the information complexity in order to better exploit it. This three-dimensional view allows reflecting the information complexity in order to better exploit it. In distributed information sources system, relevant information cannot be isolated. It has a content that is in connection with other contents in information network, and is used for a certain purpose, itself in relation to other uses and other contents. The main point of this work is to contribute to information system (IS) agility and enable selforganization of distributed IS (distributed Information Sources) networking structured.

Keywords: agility, complexity, service discovery, self organisation, information semantic.

An Clustering Algorithm for Block Mobility in Ad-hoc Network

Hua Long, Joan Lu, Guantao Shao and Jim Yip

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 7-11

Abstract: This paper presents a block mobility judgment that uses the matrix of similarity neighbor at the different time according to character of block mobility. A new clustering algorithms, called Block Mobility Over Clustering Algorithm (BMOC), is proposed based on a block mobility judgment and traditional LCC (Least Cluster-head Change) algorithms. The performances of the algorithm are analyzed by simulation experiments. The results show that BMOC algorithm can significantly improve the performances when there is block mobility in network than LCC’s.

Jin Tian

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 12-16

Abstract: The ECMA-368 system has been considered as one of the most potential solutions for the Physical layer (PHY) and Medium Access Control (MAC) of the next generation of WPANs. In addition to the high PHY data rates, the ECMA-368 system provides also high MAC efficiency, especially for the high speed burst transmission and frames of small size. In this work we concentrate on the analysis of ECMA-368 MAC layer efficiency via calculating the Theoretical Maximum Throughput (TMT) and network throughput. The numerical results are presented for the efficiency evaluation of ECMA-368 MAC.

Performance of Static Agent Architecture Using Centralized Matchmaking

Zafer Erenel, Selahattin Kuru and Atilla Elci

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 17-22

Abstract: Large-scale network environments such as the internet possess characteristics of distributed data and distributed access. This gives users a powerful mechanism for building and integrating large amounts of distributed information from diverse sources. However few support tools have been developed for users to sift through this vast amount of information. In this paper, agent-based information architecture is introduced aiming to assist user in gathering and integrating distributed information. Initially, integration of two entities, task agent and user agent, is examined. User agents create a user profile, and task agent within information integration architecture provides the desired information to the user agents. Text-based information is the main interest in this work due to its high significance in our daily lives. Thus, information integration architecture gathers and combines information from multiple users and presents the end users with combined information using a task agent. Limits of the population size within this architecture are determined using centralized matchmaking.

Keywords: multiagent systems, matchmaking, static agents, task agents, e-commerce, information integration.

On the Perspective Design of MAC Protocols for Wireless Sensor Networks

Jia-ling Liu, Yan-bing Liu, Wen-xu Guo and Hong Tang

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 23-27

Abstract: Various medium access control (MAC) protocols with different objectives have been proposed for wireless sensor networks (WSNs). Majority of the works appearing in the literature are focusing only on energy efficiency. There is much more innovative work to be done at the MAC layer, such as mobility, traffic pattern, and secure issues in WSNs, but few efforts are addressing these hard unsolved problems. In this paper, we discuss and analyze the techniques referring to these issues through several typical MAC protocols for WSNs. We outline the problems of current design and present open issues in the future research of MAC protocols design for WSNs.

Keywords: energy efficiency, medium access control, mobility, security, traffic pattern, wireless sensor networks.

Theoretical Framework for Packet Scheduling in Routers

Malika Bourenane and Djillali Benhamamouch

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 28-33

Abstract: We present in this paper an algorithm for a reinforcement learning multi-agent system in order to optimize the packet scheduling problem in routers. We consider autonomous and independently learning agents and we seek to obtain an optimal solution for the set while keeping the learning as much decentralized as possible. Coordination between agents occurs through indirect communication, using mobile agents as an ant colony. We adopt the framework of Markov decision processes applied to multi-agent system and present a pheromone_Q-learning approach which combines the standard Q-learning technique with a synthetic pheromone that acts as a communication medium speeding up the learning process of cooperating agents.

Keywords: multi-agent system, reinforcement learning, MMDP, mobile agent, ant colony, packet scheduling

The Conception of Abstract Programming

Alexander V. Sosnitsky

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 34-40

Abstract: A new approach to the construction of programs is offered on the basis of the so-called closed abstract conceptual models of the World phenomena. The abstract conceptual models are deduced from the initial system of the World categories by special research of the author and represent the highest level of abstraction of the real World. The basic components of models and procedures of their processing are defined. The general mechanisms of formation and development of such models on the basis of the superlaw of the World Harmony are shown. The initial classification of harmonizers is made. The basic mechanisms of processing models as the beginning of procedures of identification, copying, abstraction, concretization, closure, virtualization, research, decision-making and realization are determined. They have universal character and result in the unification of programs. The programs finally lose the algorithmic properties and strengthen copying abilities, turning into a continuous, dynamic, cognitive and supervising process. The research has qualitative high-level abstract character for further theoretical and applied research and development.

Keywords: abstract conceptual programming, abstract World theory, artificial intelligence, closed abstract conceptual models, harmonic phenomena classification, harmonic stages, super-law of Harmony.

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 46-50

Abstract: Marketing databases are currently one of the most important resources in any marketing departments. Regarding their customer knowledge needs many of them had develop their own database repository system. Although it immediate usefulness, as long as their databases were growing that behavior had revealed insufficient and created others barriers to their customer knowledge acquisition process, like data quality or data heterogeneity problems. This paper focuses one relationship marketing program that was conceived to be supported by a huge marketing database. Although database’s dimension it has many structural problems that had conditioned the initial approach. During his work it was proposed and developed a knowledge discovery in databases process using data mining algorithms in order to answer to marketers’ questions: which customers uses a promotional voucher? Which are they main characteristics?. The results show great promise as the predictive accuracy of the integrated self organized maps with decision tree C5 algorithm.

Success Factors for Retail Logistics in an E-Commerce-Environment

Anke Jasper and Matthias Klumpp

Sinoeuropean Engineering Research Forum, Vol. 1, July 2008, pp. 63-68

Abstract: Retail logistics by itself is a complex task due to different products, time schedules and lot sizes. In e-commerce suitable e-logistics processes are usually one of the cornerstones of a successful online retail channel. But as this analysis of success factors for e-logistics in the online environment shows, the realtionship is also characterised by dependencies the other way round as logistics depends on e.g. attractive and online presentable products as well as low return ratios of the product sold online. Therefore e-logistics and e-commerce should be developed together in retail companies in order to achieve a successful supply chain and business model.

Keywords: e-logistics, e-commerce, retail logistics, success factor analysis.
