I. Abstract

The project demonstrates that the creation of a functional wireless mesh network (WMN) is

possible using off the shelf components. Routers were configured to allow data to hop wirelessly

from one router to the next before reaching its destination. This network was designed to handle

common Internet tasks such as email, web browsing and file transfers. In addition, automation

scripts allowed these routers to be easily deployed without any infrastructure requirements.

Implementing such a network included hardware and software considerations needed to support

wireless communications and allow clients to easily connect through the network to access

another external network. Design of a routing scheme to handle traffic from a client, within the

mesh network and to an external network was required.

Testing of the network was done to determine the affect the number of hops a packet must take to

reach its destination and had on throughput and round trip time. The fairness between two clients

at different location of the network was also tested. To do this, traffic generators and common

user tasks such as file transfers were used, while varying the configuration of the network.

The network was successfully implemented reaching a maximum of four hops, limited by

hardware resources of the project. Although Internet tasks could be done on the network, a

memory leak with the open source driver for the wireless network devices, full testing results

were not obtained.

This report outlines the configuration of the mesh router hardware and how the software system

on these machines was implemented to have them behave as mesh routers, joining together to

form a WMN. The report also contains the testing information that was able to be collected even

with the malfunctioning driver.
