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

ABSTRACT

ZigBee is a low-cost, low-power, wireless mesh networking proprietary standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries, and the mesh networking provides high reliability and larger range.

The ZigBee Alliance is an association of companies working together to enable reliable, cost-effective, low-power, wirele ....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

Demystifying 802.15.4 and ZigBee



ZigBee

ZigBee is a protocol that uses the 802.15.4 standard as a baseline and adds additional routing and networking functionality.
The ZigBee protocol was developed by the ZigBee Alliance. The ZigBee Alliance is a group of companies that worked in
cooperation to develop a network protocol that can be used in a variety of commercial and industrial low data rate
applications. ZigBee is designed to add mesh networking to the underlying 802.15.4 ....etc

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

IEE 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 laptops and ....etc
