Overview A wireless Local Area Network (LAN) is a moderate to high-speed flexible data communications system implemented as an extension to, or as an alternative for, a wired Local Area Network (Kolawole, 2014). In wireless LAN transmission making use of radio frequency to communicate over the air eliminates or at least minimizes the use of physically wired networks. From the beginning, IEEE 802.11 was designed to look and feel like IEEE 802 wired networks to include supporting all of the protocols
Detecting Wireless LAN MAC Address Spoofing Abstract An attacker wishing to disrupt a wireless network has a wide arsenal available to them. Many of these tools rely on using a faked MAC address, masquerading as an authorized wireless access point or as an authorized client. Using these tools, an attacker can launch denial of service attacks, bypass access control mechanisms, or falsely advertise services to wireless clients. This presents unique opportunities for attacks against wireless networks

Wireless LANs have expanded greatly and rapidly in recent years. The expansio¬¬¬¬¬n has caused many benefits to the end users but at the same time it has introduced problem of overlapping BSS (Basic Service Set) where BSS (i.e. WLAN cells) is fundamental block of IEEE 802.11 WLAN architecture. OBSS occurs due to two or more unrelated BSSs are used at the same place, at the same time and with the same frequency channel. With the expansion of channel bandwidth to 80 MHz (may be, 160 MHz) in upcoming
1. Introduction • Wi-Fi also common spell with Wifi or interCap word WiFi, is one of the most popular wireless communication standards on the market that exchange data or internet by wirelessly using radio waves. Wi-Fi is technically a trademarked brand name for the wireless standard owned by the Wi-Fi Alliance, much like Bluetooth® is trademarked by the Bluetooth Special Interest Group. The Wi-Fi Alliance also defines Wi-Fi as any WLAN product that based on the IEEE 802.11 standard. However, only
Introduction Wireless networks have grown in popularity. This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in 'Metcalf's law.' Metcalf's law states that if you 'connect any number, 'n,' of machines - whether computers, phones or even cars - and you get 'n' squared potential value.'[1] The incredible growth of the Internet seems to validate Metcalf's law. It then seems
Area Network (LAN) to access MMLS for example. While when connected to outside through internet, we call it Wide Area Network (WAN). We are connected to the world via various network topologies, such as Point-to-point, Bus, Star, Ring, Mesh, Tree, Hybrid, and last but not least Daisy chain. Our interest regarding this Final Year Project is Wireless Mesh Network build based on Mesh Topology. 1.2 Motivation This project is motivated by the application that can be utilized using a wireless mesh network
during their careers and help in developing new and beneficial technologies. Such examples of this emerging technology include: the development of Motor Vehicle Event Data Recording systems for vehicle safety, improving standards of connectivity for wireless devices and networking, and researching possible alternative energy resources and solutions to promote energy conservation for the community. First, the Institute of Electrical and Electronics Engineers (IEEE) is the largest professional organization
There are many reasons why wireless networks are used. One reason is for a temporary backup to an existing broken cable network. Cable networks can leave many users disconnected from the network by one bad or broken cable. When this happens a wireless network may help to get these users connected until they can be reconnected through or repaired cable. This also leads to the usage of wireless networks being used as a backup. It would be much easier to connect the disconnected users to the network
Most Common Wireless Networking Access Methods Wireless communication has created an ever-evolving need for devices that are faster and applicable to a variety of lifestyle situations. As new devices are created, security measures have to be implemented and policies have to be adapted as the way we live changes in response to the technology available to us. Two of the most common wireless communication access methods are Bluetooth and WiFi. Bluetooth technology creates personal area connections
Scope and Objective Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia
or simply not caring enough to address them. For instance, one of the most basic vulnerabilities and exposures that a person can present for them is simply leaving open access to their wireless broadband router that was purchased at al local technology shop. This may not seem like such a bid deal, but an open wireless connection is essentially an open invitation for a snooper to look into an individual’s personal life. This has the potential to address all of the fallout scenarios... ... middle of
