could have been another wireless or an Ethernet card. We tested our network with both the U.S.

Robotics USR2410 and the Realtek Ethernet card. Please see Section 3.2 for more details. This

configuration preformed network address translation (NAT) on the packets in order to pass them

from one device to the other. Packets not addressed to the host would be forwarded to the

appropriate router. The operation of this configuration can be broken down into 7 main parts, as

can be seen in Figure 5-3.

5.3.3

Internet Gateway Router Configuration

Similar to the Client Gateway Router Configuration, this configuration expected the machine to

have two devices, one of which was the wireless device used to participate in the mesh network.

The other device was an Ethernet adapter. In the mesh network created, the DWL-AG530 card

was used for as the mesh wireless communication device, and the Realtek Ethernet card was used

to send packets to the external network. Please see Section 3.2 for more details. In order to pass

packets from one device to the other, network address translation (NAT) was preformed. The

operation of this configuration can be broken down into the same 7 main blocks, as the Client

Gateway Router Configuration was. Please see Figure 5-3 for more details about the interaction

between the blocks.

Block Descriptions

In this section a detailed description of each main block of the above configurations is given. All

of the blocks had similar functionality in all the configurations. If a major difference in

functionality between two configurations existed, it is noted in the block descriptions. In the

diagrams, the different paths are contained in one box.
