Framing and Schedule Dissemination for Multi-hop TDMA-based Wireless Networks

TDMA-based protocols with a connection setup mechanism can be used to provide QoS guarantees in a network. Wireless Mesh Networks (WMNs) are multi-hop in nature and supporting QoS intensive application on them requires multi-hop TDMA-based protocol. However, most designs of TDMA-based protocols are limited to single-hop based settings.

In this work, we have designed, implemented and evaluated a centrally-controlled TDMA-based MAC protocol for multi-hop wi ....etc

Abstract—We implement a new software-based multihop TDMA MAC protocol (Soft-TDMAC) with microsecond synchronization using a novel system interface for development of 802.11 overlay TDMA MAC protocols (SySI-MAC). SySI-MAC provides a kernel independent message-based interface for scheduling transmissions and sending and receiving 802.11 packets. The key feature of SySI-MAC is that it provides near deterministic timers and transmission times, which allows for implementation of highly synchronized TDMA MAC protocols. Building on SySI-MAC's predic ....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

IDENTIFICATION OF GROUND WATER POTENTIAL ZONE BASED ON INDEX OVERLAY METHOD IN AND AROUND DEHRA DOON
Abstracts
The last decade has seen a phenomenal growth in the use of Remote Sensing and GIS technology in ground water studies as the ground water has become the most sought-after natural resource by the mankind due to tremendous pressure on the ground water system by the ever-increasing population and industrial growth. Since last decade, the value per barrel of potable ground water has outpaced the value of ....etc
