Data Security has become a very serious part of any organizational information system. Internet threats have become more intelligent so it can deceive the basic security solutions such as firewalls and antivirus scanners. To enhance the overall security of the network an additional security layer such as intrusion detection system (IDS) has to be added. The anomaly detection IDS is a type of ID...

this paper presents a dual simulation environment for simulating different type of telecommunication networks integrating intelligent agents. Agents are considered as advanced tools for resolving complex issues in networking based on intelligent and dynamic features. To test the efficiency of these proposals, new simulation environments, integrating both agents and network components, are requi...

Historical examples (ISDN, Teletex, telefax, telex) show us that forecasting efforts in the telecommunication sector can go awry – not only by a few percentage points but by large magnitudes. We maintain that with strong network effects it is not possible to forecast the success of telecommunication services with a high degree of confidence. This paper reviews the role played by network effects...

With the rapid evolution of telecommunication networks, real-time network traffic management is becoming more and more crucial. We propose here a modular system for performing diagnosis at different levels of the network. It is designed as an aid to the operator. We present results of different experiments with a first version of this system which operates at a local level.

Understanding the individual behavior has shown to be of paramount importance to the triumph of the telecommunication operators to retain customers, enhance their purchasing capacity, and predict the churn rate. Different behavior patterns can be observed for different groups of users. Hence, there is an interesting problem posted in telecommunication network that how to define the users’ role ...
