38 // This is an example that illustrates how 802.11n aggregation is configured.
39 // It defines 4 independent Wi-Fi networks (working on different channels).
40 // Each network contains one access point and one station. Each station
41 // continuously transmits data packets to its respective AP.
42 //
43 // Network topology (numbers in parentheses are channel numbers):
44 //
45 // Network A (36) Network B (40) Network C (44) Network D (48)
46 // * * * * * * * *
47 // | | | | | | | |
48 // AP A STA A AP B STA B AP C STA C AP D STA D
49 //
50 // The aggregation parameters are configured differently on the 4 stations:
51 // - station A uses default aggregation parameter values (A-MSDU disabled, A-MPDU enabled with maximum size of 65 kB);
52 // - station B doesn't use aggregation (both A-MPDU and A-MSDU are disabled);
53 // - station C enables A-MSDU (with maximum size of 8 kB) but disables A-MPDU;
54 // - station D uses two-level aggregation (A-MPDU with maximum size of 32 kB and A-MSDU with maximum size of 4 kB).
55 //
56 //Packets in this simulation belong to BestEffort Access Class (AC_BE).
57 //
58 // The user can select the distance between the stations and the APs and can enable/disable the RTS/CTS mechanism.
59 // Example: ./waf --run "wifi-aggregation --distance=10 --enableRts=0 --simulationTime=20"
60 //
61 // The output prints the throughput measured for the 4 cases/networks described above. When default aggregation parameters are enabled, the
62 // maximum A-MPDU size is 65 kB and the throughput is maximal. When aggregation is disabled, the throughput is about the half of the physical
63 // bitrate. When only A-MSDU is enabled, the throughput is increased but is not maximal, since the maximum A-MSDU size is limited to 7935 bytes
64 // (whereas the maximum A-MPDU size is limited to 65535 bytes). When A-MSDU and A-MPDU are both enabled (= two-level aggregation),
65 // the throughput is slightly smaller than the first scenario since we set a smaller maximum A-MPDU size.
66 //
67 // When the distance is increased, the frame error rate gets higher, and the output shows how it affects the throughput for the 4 networks.
68 // Even through A-MSDU has less overheads than A-MPDU, A-MSDU is less robust against transmission errors than A-MPDU. When the distance is
69 // augmented, the throughput for the third scenario is more affected than the throughput obtained in other networks.
