AN ADVANCED MAC PROTOCOL MIMO WLANS


INTRODUCTION
WLANS can be largely benefited by utilizing distributed spatial multiplexing gain that can be achieved by cancelling multiuser interference using multiple antennas at transmitter/receiver side. However, the distributed coordination function (DCF) which is the fundamental channel access method of IEE 802.11n is based on CSMA/CA and thereby prevents the distributed spatial multiplexing by collision avoidance scheme

Wireless MAC Protocol Using Implicit Pipelining (Java)
IEE Transactions on Mobile Computing, Vol. 5, No. 3,


Abstract: In distributed multiple access control protocols, two categories of overhead are usually associated with contention resolution. One is channel idle overhead, where all contending stations are waiting to transmit. Another is collision overhead, which occurs when multiple contending stations attempt to transmit simultaneously. Either idle overhead or collision overhead being large, contention resolution algorithm wou ....etc

MIMO RADAR SIGNAL PROCESSING:MIMO as a Distributed Radar System
ABSTRACT:

Multiple-input multiple-output (MIMO) radar has been receiving increasing attention in recent years from researchers, practitioners, and funding agencies. MIMO radar is characterized by using multiple antennas to simultaneously transmit diverse (possibly linearly independent) waveforms and by utilizing multiple antennas to receive the reflected signals. Like MIMO communications, MIMO radar offers a new paradigm for signal processing research. MIMO radar possesses sig ....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 IEE 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 IEE 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 IEE 802.11 DCF in the highly mobile vehicular networks. We first propose a simple yet accurate ....etc
