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

Maximizing Unavailability Interval for Energy Saving in IEEE 802.16e Wireless MANs
Tuan-Che Chen Jyh-Cheng Chen Ying-Yu Chen Nat. Tsing Hua Univ., Hsinchu;
This paper appears in: Mobile Computing, IEEE Transactions on Publication
Abstract
This paper presents an energy conservation scheme, Maximum Unavailability Interval (MUI), to improve the energy efficiency for the Power Saving Class of Type II in IEEE 802.16e. By applying the Chinese Remainder Theorem, the proposed MUI is guaranteed to find the maximum Unavailability Interva ....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

Introduction

Sensors integrated into structures, machinery, and the environment, coupled with the efficient delivery of sensed information, could provide tremendous benefits to society. Potential benefits include: fewer catastrophic failures, conservation of natural resources, improved manufacturing productivity, improved emergency response, and enhanced homeland security . However, barriers to the widespread use of sensors in structures and machines remain. Bundles of lead wires and fiber optic ....etc
