Abstract
We analyze the MAC access delay of the IEEE 802.11e EDCA mechanism under saturation. We develop a detailed analytical model to evaluate the influence of all EDCA differentiation parameters, namely AIFS, CWmin, CWmax and TXOP limit, as well as the backoff multiplier beta. Explicit expressions for the mea ....etc

BANDWIDTH ESTIMATION FOR IEEE 802.11 BASED ADHOC NETWORK
Abstract: Since 2005, IEEE 802.11-based networks have been able to provide a certain level of quality of service (QoS) by the means of service differentiation, due to the IEEE 802.11e amendment. However, no mechanism or method has been standardized to accurately evaluate the amount of resources remaining on a given channel. Such an evaluation would, however, be a good asset for bandwidth-constrained applications. In multihop ad hoc networks, such evaluation becomes even more difficult. C ....etc

Abstract
IEEE 802.16 standard and WiMAX (Worldwide Interoperability of Microwave Access) will standardize and promote wireless broadband as a wireless alternative to digital subscriber line (DSL) and cable that can help remove barriers to broadband access by providing last mile connectivity. The standard reduces costs, improves security, throughput and makes the connection more exible and scalable. WiMAX operates using a base station and a subscriber station with the base station controlling access within a cell. WiMAX could als ....etc

IEEE 802.11n “Next Generation Wireless Standard
ABSTRACT

The newest standard in Wireless LAN is called 802.11n. 802.11 is an industry standard for high-speed networking. 802.11n is designed to replace the 802.11a, 802.11b and 802.11g standards. 802.11n equipment is backward compatible with older 802.11gab and it supports much faster wireless connections over longer distances. So-called Wireless N or Draft N routers available today are based on a preliminary version of the 802.11n. The beta version of this standard is used now in lapto ....etc

Performance Analysis of CSMA/CA protocol in IEEE 802.11 Networks using Backoff mechanism

Abstract: The distributed coordination function (DCF) in the IEEE 802.11 standard for wireless LAN is based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) like medium access control protocol. This collision avoidance is implemented by means of backoff procedure which uses a rotating window mechanism. This paper presents a simulation analysis of the slot selection probabilities and the backoff mechanism. The ....etc
