Intrusion Handling Systems for Wireless LANs

Algirdas Pakstas and Shahram Salekzamankhani
London Metropolitan University, UK

A number of mechanisms and techniques have been used for defending network resources. Firewalls, encryption, authentication, vulnerability checking and other techniques can all help to enhance the network security. However, Wireless LANs (WLANs) are coming with embedded flaw such as potentially reduced security. This was reflected in many publications and research towards building more secure WLANs is still undergoing. The main problem with WLANs is due to its nature because intrusion (unauthorised access) may happen without intruder (unauthorised user) no longer is gaining physical access to the network in order to compromise its security. This tutorial review concepts related to Intrusion Handling Systems for WLANs.

RFID –

Radio Frequency Identification: Technology Basics and Business Uses

 

Gottfried Luderer, Arizona State University, USA

 

   Imagine that arbitrary objects and even people or animals can carry a small inexpensive tag, replacing the ubiquitous bar code by something like a cheap piece of circuitry – costing just a few cents. And furthermore that this tag can be read from a short distance of a few meters without the need for a line-of- sight connection. The tag can be coded with its own unique identification. The tag does not need its own power source but is discovered by nearby reading devices sending short inquiry messages and listening to the coded “back scattered” responses.

   The underlying technology has been around for many years, but it is just getting mature enough to become practically useful. RFID is in the process of widespread introduction, for monitoring merchandize in the supply chain from manufacturer to customer, e.g. at Walmart, to inclusion in your passport or implanting tags in your dog. This seminar will briefly survey the technology and look at various business applications.  RFID categories like active and passive tags will be discussed as well as system architectures. What are obstacles to its introduction, technical and political, and potential benefits as well as abuses? Of all recently introduced electronic technologies, RFID may have the largest impact on our daily lives in the coming years.


Biography: Dr. Gottfried W. R. Luderer was appointed Professor, ISS Chair of Telecommunication, at Arizona State University in the Fall of 1990. His current research program in networking includes work in the areas of control of ISDN/Broadband ISDN networks, mobile communication networks, and multimedia communication, which ranges from call processing for intelligent network services to network management. Research emphasis is on advanced software technologies for development of telecommunication networks, as used in switches, for signaling and in network management, with a focus on object and component technology and formal definition techniques. From 1965 to 1989, Dr. Luderer was with AT&T Bell Labs, at last directing research on next generation switch architectures, based on fast packet switching technology on the hardware side and object-oriented design technology on the software side, resulting in some of the earliest demonstration networks for multimedia communication. Dr. Luderer holds Diplomingenieur (M.S) and Dr.-Ing. (Ph.D) degrees in Electrical Engineering from the Technical University of Braunschweig, Germany. He holds two patents. While at Bell Labs, he taught at Stevens Institute of Technology in Hoboken, NJ, and at Princeton University. He is member of ACM, IEEE, IEEE Computer and Communication Societies.

 

IP-Oriented QoS in the Next Generation Networks: application to wireless networks

Pascal Lorenz, Universite de Haute Alsace, FRANCE  

Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. The "best effort" Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed QoS services as well as high rate communications.
The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough resources available in some parts of the  network the mobile user is moving into. The emerging Internet QoS architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.
This tutorial covers to the issues of QoS provisioning in heterogeneous networks and Internet access over future wireless networks as well as ATM, MPLS, DiffServ, IntServ frameworks. It discusses the characteristics of the Internet, mobility and QoS provisioning in wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking protocols and end to end traffic management issues.

Fundamentals of Grounding Design

Elya Joffe, K.T.M. Project Engineering, Izrael

 

ABSTRACT: “One of the problems with grounding is the term itself... it’s too vague; Often a single ground may serve multiple needs, with different rule to each”
The discipline of Electromagnetic Compatibility (EMC) is concerned with the design of Electronic Systems, while minimizing electromagnetic coupling and interference from within the system and between the system to its environment. The discipline of electromagnetic compatibility covers and requires involvement in a wide range of other fields of engineering, system engineering and electronic engineering, etc.
The concept of “grounding” is probably among the most important, yet less understood topic of electronic design, often considered as "black magic". Yet – grounding forms an inseparable part of all electronic and electrical designs, from circuit through system up to installation design. Grounding is implemented for EMC and ESD protection, for safety purposes, for lightning and surge protection, etc.
This presentation is intended to shed some light on the concepts and pitfalls associated with grounding - an essential and inseparable concept in EMC design.
The presentation will cover the rational and fundamental concepts of grounding and its topologies, leading to the implementation of grounding from circuit to system. Practical applications will be extensively discussed. Practical solutions to practical problems, as well as “real life case studies” are used as examples.
