Tutorial at IEEE 802 LMSC Plenary Session, Dallas, TX, USA, Nov. 13, 2006 (with W. Steven Conner, Intel Corp., Jan Kruys, Cisco Systems, and Juan Carlos Zuniga, InterDigital Comm. Corp.).
An open, unencrypted wireless network can 'sniff' or capture and record the traffic, gain unauthorized access to internal network resources as well as to the internet, and then use the information and resources to perform disruptive or illegal acts.Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security. Wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.The risks to users of wireless technology have increased as the service has become more popular.As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.

The following resources come from the 2009/10 BSc in Computer and Network Technologies (course number 2ELE0072) from the University of Hertfordshire. All the mini projects are designed as level two modules of the undergraduate programmes.
The objectives of this module are to Demonstrate within a private network environment:
• The implementation of a wireless local are networks (WLANs) topology with diverse physical parameters
• The real-time performance evaluation of the individual WLAN transmission characteristics in the presence of standard transport protocols.
This mini-project involves the implementation of an “infrastructure” wireless network, the generation and transmission of packets and the measurement of network performance for TCP transport protocols by means of the “Wireshark” benchmarking tool. Parameters most likely to affect network performance such as the transmission medium’s signal-to-noise ratio, the propagating signal’s latency and jitter and the packet loss rate will be determined.
2.4 GHz Open band
Globally available
Other devices include microwave ovens, cordless phones
Frequency hopping and Time Division Multiplexing
10 – 100 meter range
Up to 8 active devices can be in the same piconet
Wireless networks are accessible to anyone within the router’s transmission radius. This makes them vulnerable to attacks. Hotspots are available in public places such as airports, restaurants, parks, etc.
In this module, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks.
Comparative study of various voip applications in 802.11 a wireless network s...ijmnct
Today, Voice over Wireless Local Area Network (VOWLAN) is the most accepted Internet application.
There are a large number of literatures regarding the performance of various WLAN networks. Most of
them focus on simulations and modeling, but there are also some experiments with real networks. This
paper explains the comparison of performance of two different VOIP (Voice over Internet Protocol)
applications over the same IEEE 802.11a wireless network. Radio link standard 802.11a have maximum
transmission rate of 54Mbps. First protocol is session initiation protocol (SIP) and second is H.323
protocol. First one has an agent called SIP proxy. Second have a gateway reflects the characteristics of a
Switched Circuit Network (SCN). With this comparison we have required to obtain a better understanding
of wireless network suitability for voice communication in IP network.

DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:

Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.
Now let’s talk about interference Previous slide covered non-bursty weak interference Make this not look like directional antennas (broadcasts, waves) Distance, trees attenuate signal Delivery probability depends in part on signal-to-noise ratio P(delivery) = f(S/N) Perhaps many Roofnet node pairs have S/N corresponding to intermediate delivery probabilities Mention S/N measurements calibrated in the lab Replace hypothesis slides w/ pictures Mention s/n reported by the card Don’t #2 make it sound so definite Qualify the second point Mention ‘textbook model of ber’
We’ve eliminated the possibility that we’re losing bursts of packets We’ve narrowed the possibilities enough that we know we’re losing packets individiually “ the important special case” Start the explanation of this hypothesis here Why two phases? Mention it’s all beacons, constant, 8 APs XXX Roofnet shares its 802.11 channel with the rest of Cambridge XXX Other 802.11 traffic could corrupt our traffic at a time-scale of individual packets, without affecting our S/N measurements (xxx what’s the experiment?)
