INTRODUCTION

The genesis of this work is the interest of the Portuguese Navy in measuring physical parameters over long distances, as the result of an impact of a missile in a naval platform. The analysis of those parameters may provide information about the effects of the impact ....etc

ZigBee/IEE 802.15.4 Summary

Introduction
1.1 Evolution of LR-WPAN Standardization
The cellular network was a natural extension of the wired telephony network that became pervasive
during the mid-20th century. As the need for mobility and the cost of laying new wires increased,
the motivation for a personal connection independent of location to that network also increased.
Coverage of large area is provided through (1-2km) cells that cooperate with their neighbors to
create a seemingly seamless network. Examples of ....etc

FEBA: A Bandwidth Allocation Algorithm for Service Differentiation in IEE 802.16 Mesh Networks
Cicconetti, C. Akyildiz, I. F. Lenzini, L.
This paper appears in: Networking, IEE/ACM Transactions on Publication
Abstract
In wireless mesh networks, the end-to-end throughput of traffic flows depends on the path length, i.e., the higher the number of hops, the lower becomes the throughput. In this paper, a fair end-to-end bandwidth allocation (FEBA) algorithm is introduced to solve this problem. FEBA is implemented at the medium access ....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 wireless net ....etc

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

Abstract: The distributed coordination function (DCF) in the IEE 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 obt ....etc

BANDWIDTH ESTIMATION FOR IEE 802.11 BASED ADHOC NETWORK-MOBILE COMPUTING

Abstract: Since 2005, IEE 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 IEE 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 ....etc

Abstract: In this paper, we propose an accurate method to evaluate the available bandwidth in IEE 802.11-based ad hoc networks. We improve the method described in. We evaluate our solution on di_erent scenarios. We also provide a comparison with different QoS routing protocols, BRuIT, AAC and QoS-AODV, based on di_erent available bandwidth estimation techniques.

Maximizing Unavailability Interval for Energy Saving in IEE 802.16e Wireless MANs
Tuan-Che Chen Jyh-Cheng Chen Ying-Yu Chen Nat. Tsing Hua Univ., Hsinchu;
This paper appears in: Mobile Computing, IEE 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 IEE 802.16e. By applying the Chinese Remainder Theorem, the proposed MUI is guaranteed to find the maximum Unavailability Interval, du ....etc
