A new SDN-based framework for wireless local area networks
Nowadays wireless networks are becoming important in personal and public communication andgrowing very rapidly. Similarly, Software Dened Network (SDN) is an emerging approach to over-come challenges of traditional networks. In this paper, a new SDN-based framework is proposedto ne-grained control of 802.11 Wireless LANs. This work describes the benets of programmableAcc...
متن کاملInterworking between High-speed Portable Internet and Existing Wireless LANs using Different AAA Protocols
With the growth of wireless technologies rapidly, there will be coexist heterogeneous wireless LANs environment within a few years. For example, there may be coexist current wireless LAN systems based widely available 802.11 and a wireless LAN system based proprietary wireless LAN standard with different AAA mechanisms such as RADIUS and Diameter. In case of being coexisted the heterogeneous wi...
متن کاملA Mobile Agent Based Architecture for Securing WLANs
Wireless LANs are open and are vulnerable to various attacks. Techniques available to prevent Wireless LANs from these attacks are not comprehensive. In this paper we discuss the drawbacks of the existing security mechanisms and we provide a security architecture which uses Mobile agents as a security facilitator. Using this architecture, users have freedom to choose from a variety of encryptio...
متن کاملAn investigation into the unauthorised use of 802.11 wireless local area networks
The use of 802.11 wireless local area networks (LANs) is growing at a phenomenal rate. However, numerous flaws have been discovered in WEP, and studies have shown that many wireless LANs are installed with their default settings. These are soft targets for war drivers, who drive around with laptops and 'cantennas' locating insecure wireless LANs. While it is known that wireless LANs experience ...
متن کاملIndoor Optical Wireless Communication Systems – Part I: Review
The emergence of portable computing devices such as laptops, palmtops and personal digital assistants (PDAs) has fuelled the demand for mobile connectivity and hence, led to the development of wireless local area networks (LANs). Wireless LANs offer users increased mobility and flexibility compared with traditional wired networks, and may be classified as either infrastructure wireless or ad ho...
متن کاملQoS Routing for Mesh-Based Wireless LANs
Wireless LANs with their increased data rate become an attractive technology for connecting mobile users to the Internet. Efficient deployment of wireless LANs will require the ability to extend the wireless LANs coverage without the need to deploy a very large number of access points. Mesh based wireless LANs are an attractive solution to this problem. These networks extend the wireless LAN co...
