Abstract
The third generation(3G) wireless network is envisaged as the next generation wireless solution for meeting the demand of its users. It promises to provide wireless access to multimedia applications at rates upto 2Mbps. But the problems of intermittent disconnection, high error rate in wireless networks can cause degradation of protocols and compromise the QoS (Quality-of-Service) guaranteed to the users. So, there is a need for adaptive protocols, which, on determining the current adverse wireless network conditions, adapt t ....etc

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 .

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

Distributed Medium Access Control for Next Generation CDMA Wireless Networks

Generic Distributed Network Model
we focus on a generic network model where a number of wireless mobile nodes are organized in a flat fashion, communicating with each other via one-hop or multiple-hop connections without any central control. Connections to outside correspondence nodes are supported through a gateway (e.g., in the wireless backbone) or an access point (e.g.,in ad hoc networks or WPAN).

ABSTRACT
We propose a CDMA-based power controlled medium accessprotocol for mobile ad hoc networks (MANETs). Unlikepreviously proposed protocols, ours accounts for the multipleaccess interference (MAI), thereby addressing the notoriousnear-far problem that undermines the throughputperformance in MANETs. Channel-gain information obtainedfrom overheard RTS and CTS packets over an outof-band control channel is used to dynamically bound thetransmission power of mobile terminals in the vicinity ofa receiver. By properly estimating the requi ....etc

INTRODUCTION
1.1 HISTORY OF WIRELESS COMMUNICATION
In the history of wireless technology, the demonstration of the theory of electromagnetic waves by Heinrich Rudolf Hertz in 1888 was important. The theory of electromagnetic waves was predicted from the research of James Clerk Maxwell and Michael Faraday. Hertz demonstrated that electromagnetic waves could be transmitted and caused to travel through space at straight lines and that they were able to be received by an experimental apparatus.
