White Paper Approval of the IEEE 802.11 standard for wireless local area networking (WLAN) and rapid progress made toward higher data rates have put the promise of truly mobile computing within reach. IEEE 802.11 is limited in scope to the Physical (PHY) layer... [02 Sep 2008]
Understanding Wi-Fi
White Paper Once confined only to specialty niches, wireless networks are now beginning to proliferate in the form of IEEE 802.11b (Wi-Fi) wireless LANs, allowing users to roam throughout a building with a laptop while still remaining connected to their network. [02 Sep 2008]
Mandating QoS in Wireless LANs
White Paper Similarly, the wireless LAN MAC protocol defined in the standard IEEE 802.11 was designed for data networks. Tripleplay - Data, voice and video services over an integrated or converged network is much talked about these days. [04 Aug 2008]
An Adaptive Multimedia QoS Scheduler for 802.11e Wireless LANs
White Paper The IEEE 802.11e standard defines the Hybrid Coordination Function (HCF) which species the QoS algorithms in the MAC layer of the next generation 802.11 Wireless LAN (WLAN). The HCF is composed of two access functions: A distributed contention... [04 Aug 2008]
Wireless LANs Standards: Where Are We Now?
White Paper By virtually any measure, the Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless local area network (WLAN) standards have achieved international success. In addition, the IEEE 802.11 committee continues to develop many new... [18 Jul 2008]
Vulnerabilities of IEEE 802.11i Wireless LAN CCMP Protocol
White Paper IEEE has recently incorporated CCMP protocol to provide robust security to IEEE 802.11 wireless LANs. It is found that CCMP has been designed with a weak nonce construction and transmission mechanism, which leads to the exposure of initial counter... [03 Jul 2008]
Quality of Service Schemes for IEEE 802.11 Wireless LANs - An Evaluation
White Paper This paper evaluates four mechanisms for providing service differentiation in IEEE 802.11 wireless LANs. The evaluated schemes are the Point Coordinator Function (PCF) of IEEE 802.11, the Enhanced Distributed Coordinator Function (EDCF) of the... [03 Jul 2008]
Performance Improvement of TCP With Delayed ACKs in IEEE 802.11 Wireless LANs
White Paper This paper uses a Markov renewal reward approach to analyse the throughput achieved by a TCP connection spanning a multi-hop wireless network that uses the IEEE 802.11 MAC protocol. The significance of the paper is twofold - the method used in the... [03 Jul 2008]
A Unified Scheduling Approach for Guaranteed Services Over IEEE 802.11e Wireless LANs
White Paper Coordinating access to the wireless medium in an IEEE 802.11 wireless LAN is different from network layer scheduling since it requires scheduling traffic flows in a distributed manner. Supporting real-time multimedia applications in any network... [03 Jul 2008]
On Optimization of CSMA/CA Based Wireless LANs: Part I - Impact of Exponential Backoff
White Paper This paper considers optimization of CSMA/CA based wireless networks such as IEEE 802.11 Wireless LANs. A fundamental component of the MAC layer functionality in such networks is the Binary Exponential Backoff (BEB) of contending nodes which serves... [03 Jul 2008]
Enhanced Backoff Scheme in CSMA/CA for IEEE 802.11
White Paper An enhanced CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) protocol to be used in the Medium Access Control (MAC) layer of the IEEE 802.11 standard for Wireless Local Area Networks (wireless LANs) is proposed in this paper. [03 Jul 2008]
Firebox SOHO6 Wireless Integrated Security for SME Wireless Networks
White Paper Wireless LANs (WLANs) based on IEEE 802.11 standards have all the characteristics viz. WLANs are cheap, easy to install, and without question beginning to capture the LAN marketplace. WLANs have a very positive disrupting effect: they deliver ample... [03 Jul 2008]
Wireless 802.11 Security with Windows XP
White Paper IEEE 802.11, 802.11a and 802.11b (also known as Wi-Fi) are wireless local area networking (LAN) standards that supply 1 megabit per second or above of bandwidth. Because these networks differ from wired LANs, several issues unique to wireless LAN... [03 Jul 2008]
802.11 Wireless LAN Security White Paper
White Paper This white paper: Reviews the authentication and data-privacy functions described in Clause 8 of the IEEE 802.11 specification, describes the inherent security vulnerabilities and management issues of these functions, explains how security issues... [03 Jul 2008]
802.11 Wireless LANs: the Future of Business Networking?
White Paper The IEEE 802.11 scheme introduces a new method for interconnecting network devices…by using radio frequency (RF) or infrared waves instead of cables. In a business context, local area network (LANs) implementations have traditionally been a... [03 Jul 2008]
