demonstration purposes, so wireless communication could easily be added without the risk of

using unsupported hardware. Also, there were reports that machines could not be configured with

two cards both containing Atheros chipsets. Since the most common chipsets for cards

implementing the wireless 802.11g standard is the Atheros chipset, and this information is not

advertised on the product, the 802.11b standard was more attractive. The low data rate did not

adversely affect the network, since wired connections were used for testing purposes.

System Hardware Configurations and Integration

Not all routers require the same hardware configuration in the network created. Some would

need to connect to external networks, whereas others would communicate only with other mesh

routers. Although the systems were designed to be similar there were variations in hardware

configurations done in order to meet these specific requirements. All configurations contain the

D-Link DWL-AG530 802.11a cards to perform mesh communication. The different hardware

configurations were: Packet Forwarding, Gateway Router Support, Wired and Wireless Client

Support.

3.3.1

Packet Forwarding

The first configuration was the most basic configuration and is referred to as a packet forwarding

router in the report. These machines had one D-Link DWL-AG530 802.11a wireless card. The

single purpose of these routers was to forward packets from one mesh router to. These routers

looked at a packet’s destination, as described Chapter 5, and determined the path the packet

needed to take. These routers were found within the mesh network, and did not have the

hardware or configuration to be connected to the Internet or to allow clients to connect. Figure

3-1 below shows the configuration of one of these devices.
