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

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 .

A decade ago, riding the devel¬opments in integrated circuit technology and the promises of Moore’s law, the concept of smart dust surfaced. Micro¬scopic devices with sensing, computing, and communication capabilities would be deployed in large numbers in the envi¬ronment to form a bridge between the digital and physi¬cal worlds.1 Along the way, however, major hurdles have blocked this goal. Node energy wasn’t sufficient to communi¬cate across large distances; short-range communications suffered from collisions and retr ....etc
