Implementation of an IEEE 802.11 Wireless LAN Model using OPNET



INTRODUCTION

Building a simulation model from a specification is a frustrating process. The specification is invariably large, seemingly unorganized, and details about important subsystem interactions can be scattered throughout the document. The document may also contain apparent (or actual) contradictions and ambiguities. Furthermore, in group projects, different interpretat..............etc

BANDWIDTH ESTIMATION FOR IEEE 802.11 BASED ADHOC NETWORK-MOBILE COMPUTING

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 ev..............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

I. INTRODUCTION
Available bandwidth estimation is a vital component of admis¬sion control for quality-of-service (QoS) in both wireline as well as wireless networks. In wireless networks, the available bandwidth undergoes fast time-scale variations due to channel fading and error from physical obstacles. These effects are not present in wireline networks, and make estimation of available bandwidth in wire..............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
