In Table 2, mode 0 refers to round-robin mode and arp_interval 100 refers to 100 msec. Table II shows the configuration on bonded interfaces. In Table 1, mode 2 corresponds to 802.11b and Rate 11M refers to 11 Mbps. Table I shows the configuration of Wi-Fi interfaces used in the experiments. The following is a list of parameters used to configure wireless and bond interfaces in these experiments. In this study we use the round-robin mode, which allocates one packet in turn to each bonded interface, achieving an even load among all interfaces. There are seven different bonding modes available in standard Linux distributions. The bond interface uses the MAC address of the first bonded interface. The wireless channels are separated by at least 5 channels to minimize inter-channel interference. The Wi-Fi interfaces on CT and CBS are set-up to link pair-wise using different ESSIDs and different wireless channels. CT is in managed mode and emulates a mobile client, whereas CBS is in master mode and represent an access point.

The PCs each have three Wi-Fi PCMCIA Atheros chipset based cards using IEEE 802.11b in the вЂњinfrastructureвЂќ mode, with the Wi-Fi driver MADWiFi. The PCs are equipped with 3.8 GHz CPU and 4 GB RAM running Redhat ES 4. Bonding was set-up on each of the two PC terminals, CT (Cognitive Terminal) and CBS (Cognitive Base Station), as shown in Figure 2. We add вЂњcognitiveвЂќ to the names of terminal and base station which have aggregation capability.

Linux Bonding was used to bond multiple wireless LAN interfaces into one logical interface. Network emulation equipment (Shunra Virtual Enterprise ModellerTM ) was used to emulate the packet loss and delay effects of traffic in the backbone network before arriving at the aggregated link. Two Linux computers (PC), each fitted with multiple Wi-Fi cards were set-up to achieve aggregated wireless links. EXPERIMENTAL TEST - BED Figure 1 shows the experimental set up used in this study.
