Introduction

What is MAC
-Controlling access to the channel
What is Z-MAC

- A Hybrid MAC which Combine the strengths of CSMA and TDMA while offsetting their weakness.

- The main feature of Z-MAC is its adaptability to the level of contention in the network .

CSMA (Carrier Sense Multiple Access)

Description : In this paper we introduced a new MAC sub-layer protocol for multi-hop Real-Time Wireless Sensor Networks (RTWSNs). This protocol makes it possible to transmit time-constrained data with given priorities and end-to-end delays. Such data are needed in multimedia applications implemented in RTWSNs. We carried out a comprehensive analysis of our protocol. Moreover, we included in this protocol a topology control mechanism which allowed us to determine the critical transmitting range. We simulated and analyzed the performance measures ....etc

The guide is created to help people solve the following problems.
(1)People who want to transfer their broken iPod's files back to iPod or iPhone.
(2)People who want to transfer their iPod files to another iPod or iPhone.
(3)People who want to manage their iPod as hard disk but not just syncing their files by using iTunes.
All the need is a smart transfer called AVCWare iPod to iPod/Computer/iTunes Transfer(For Windows) and [url=http://macdvdrippersoftipod-to-mac-transf ....etc

MAC protocols have been studied under different contexts for decades. In decentralized MAC protocols, transmitter-receiver pairs make independent decisions, which are often sub-optimal due to insufficient knowledge about the communication environment. In this paper, we introduce control-plane cooperation at the MAC layer, where neighboring nodes share control information with transmitter-receiver pairs to aid them in making more informed decisions. This augments conventional cooperation, which sits at the data plane where intermediate nodes hel ....etc

Mac OS X is a line of graphical operating systems developed, marketed, and sold by Apple Inc., the latest of which is pre-loaded on all currently shipping Macintosh computers. Mac OS X is the successor to the original Mac OS, which had been Apple's primary operating system since 1984. Unlike the earlier Macintosh operating system, Mac OS X is a Unix-based operating system built on technology developed at NeXT from the second half of the 1980s until early 1997, when Apple purchased the company. The first version released was Mac OS X Server 1.0 ....etc

Abstract—The pervasive adoption of IEEE 802.11 radios in the past decade has made possible for the easy Internet access from a vehicle, notably drive-thru Internet. Originally designed for the static indoor applications, the throughput performance of IEEE 802.11 in the outdoor vehicular environment is, however, still unclear especially when a large number of fast-moving users transmitting simultaneously. In this paper, we investigate the performance of IEEE 802.11 DCF in the highly mobile vehicular networks. We first propose a simple yet accu ....etc

Abstract

Satellite networks provides wide coverage of geographic area and high bandwidth. As satellite capacity is often limiting resource which must be used efficiently. Internet traffic is highly bursty in nature and Demand Assignment Multiple Access (DAMA) techniques are suitable provide bandwidth to match instantaneous requirements and provide significant improvements in the delay/utilization performance of Geo-stationary Earth Orbit (GEO) satellite channels supporting a finite number of users ....etc
