Introduction

1.1

Overview

The goal of this project is to create a working model of a wireless mesh network (WMN) using

off the shelf components and to gather data from test patterns to identify the utility of this type of

network. In a WMN routers are not connected via a wire to the Internet, as is done in the current

wireless networking system. Instead, data must be routed by forwarding packets via wireless

communication from clients through mesh routers to a gateway router that is connected to the

Internet. This type of network is known as a multi-hop network, since data must hop from one

router to another in order to reach its destination. In order to create such a network, appropriate

hardware must be chosen. Software must then be installed on the routers to support this hardware,

as well as to support their functionality. Finally, a routing program must be created to define the

packet flow through the network.

1.2

Purpose

The goals of the project are as follows:

• To reduce infrastructure costs for new networks.

• To create an easily deployable network.

• To design a multi-hop network to support standard user internet traffic.

• To test the effect of the number of hops and the load produced by the number of clients on the

performance of the designed network.

1.3

Scope

The intention of this project was to create a network that would handle standard internet user

traffic, including web browsing, e-mail and file transfers. Clients should be able to connect to one

mesh router at the end of the network, and have their data passed along to a gateway mesh router,

to access the Internet. The routers should use common consumer hardware, and existing network

protocols. Analysis should be preformed on the mesh network based on the number of hops, the

amount of traffic on the network and the fairness exhibited between clients on the network. Client

mobility, automatic network configuration and wireless security were outside the scope of the

project; however these would be interesting topics for extensions of this project.
