Introduction

Dublin Ad-hoc Wireless Network (DAWN) is a project undertaken by the Networks & Telecommunications Research Group (NTRG) of Trinity College Dublin that aims to build a production ad-hoc network operational in the entire city of Dublin. DAWN aims not only to be a testbed for the research undertaken at the NTRG, but also to serve as a prototype 4th Generation Mobile Network.

Aims

The basic aims of DAWN are summarised below:

Current State

Currently the Dublin Ad-hoc Wireless Network (DAWN) has successfully completed Phase 1 (end of August 2002) and is fully operational in parts of the Trinity College campus:

Applications

The NTRG has developed a number of applications that work on top of the Dublin Ad-hoc Wireless Network (DAWN):

The NTRG Protocol Stack

The NTRG ad-hoc protocol stack employs a generic layer architecture that seeks to allow a LEGO-like approach to the development and assembly of networking protocols:
