Wireless Networking Basics According to (Vacca, JR 2006) The term wireless networking means the technology that facilitates two or more computers to communicate using standard network protocols, but without network cabling. It was not a long time ago that computers were a luxury rather than a necessity.

PEAP allow safe data transfer, transport of encryption keys and passwords without involving certificate from server.
Wireless LANs provide all the functionality of wired LANs, without the physical constraints or the wired connection itself. Wireless LAN configurations range from simple peer-to-peer topologies to complex networks offering distribution data connectivity and roaming. Besides offering end-user mobility within a networked environment, wireless LANs enable portable networks, allowing LANs to move with the knowledge workers that use them. One of the aims of the project is to illustrate suitability of a wireless LAN for the in use today. This will allow us to gain a more fundamental insight in the possibilities and restrictions of wireless LAN.
Some the problems to be overcome are: (1) Data Integrity - relatively error free transmission, (2) Speed - as close as possible to the speed of current wired networks, (3) Protection - making sure that the data now airborne is encoded and cannot be tapped by unwelcome receivers, (4) Compatibility - ensuring that the many protocols that sure to be created subscribe to a standard to allow inter-operability, (5) Environmentally safe - strengths of electromagnetic radiation must be kept within normal levels. In our study of the theories and implementation concerns of wireless computing, we found that it is being treated in an object oriented fashion. Scientists and development crews, including the IEEE, are doing their best to implement wireless connectivity without changing the existing computer hardware. As a result, a lot of focus is on using existing computer hardware and software to convert data to a format compatible with the new hardware which will be added to the computer using ports or PCMCIA connections that already exist. This means that wireless communication will be transparent to the user if and when wireless computing is utilized on a wide scale.
Introduction The growth of 802.11 networks has been met with the development of several wireless local area network (WLAN) discovery applications. These applications are designed to identify WLAN activity and network characteristics, providing enough information for an unauthorized user to gain access to the target network. For obvious reasons, WLAN administrators should be concerned about unauthorized access to their networks and therefore should attempt to identify the applications used to discover their networks. WLAN intrusion analysis is not entirely unlike traditional intrusion analysis; we are primarily concerned about the identification of traffic signatures or fingerprints that are unique to the applications we want to detect. Unlike traditional intrusion analysis however, we have additional challenges that are unique to wireless networks: 1.
The following are critical security questions: • What challenges are faced with wireless security? • How can you verify that the device being used is actually in the hands of an authorized user? How can you enhance the security of the device? • How secure is the over-the-air network between the organization and the wireless device? • How can you secure the wireless session?
So in situations where there are more than a certain number('N') of hosts accessing the same wireless link, we can have an arbiter that decides which host has access to the link. In situations where there aren't enough hosts, they can fall back to an aggressive version of CSMA that doesn't have large back off timers. A hybrid approach like this will help reduce non-congestion errors on a wireless link and boost TCP performance. A robust error handling mechanism will make sure that the TCP congestion window size doesn't fluctuate unnecessarily and also avoid duplicate retransmissions and competing retransmissions.

Protection of Wireless Networks Setting security policy is important for a wireless network. Improvements in the security of wireless technology will guarantee its continued safe use, and system administrators’ duties are to take measures against unauthorized access. A media access control address (MAC address) is an identity number assigned to each network device. Most Wi-Fi access points and routers come with a function called MAC address filtering, which is a common way to improve the security of Wi-Fi access points. Without MAC address filtering, any wireless user can attempt to join wireless networks if they know the network name and security password.
Technologies happens to be speeding up to the society we currently live in. Bluetooth technologies is a short-range communications technologies that's easy, safe, and everywhere. You can discover it in billions of devices ranging from mobile phones and computers to medical devices and home entertainment goods. It's intended to replace the cables connecting devices, while sustaining higher levels of safety. The key attributes of Bluetooth technology are robustness, low power, and low price.
