This NIC implements an 802.11 network interface card in ad-hoc mode.
The following diagram shows usage relationships between types. Unresolved types are missing from the diagram.
The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.
Name | Type | Description |
---|---|---|
MobileHost | compound module |
Models a mobile host with a wireless (802.11b) card in ad-hoc mode. This model contains the new IEEE 802.11 implementation, Ieee80211Nic, and IP, TCP and UDP protocols. The mobility model can be dynamically specified with the mobilityType parameter. |
Name | Value | Description |

display | i=block/ifcard |
Name | Direction | Size | Description |
---|---|---|---|
uppergateIn | input |
to upper layers |
|
uppergateOut | output |
from upper layers |
|
radioIn | input |
to receive AirFrames |
Name | Type | Default value | Description |
---|---|---|---|
mgmt.frameCapacity | int | 100 | |
mac.address | string | "auto" |
MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0. |
mac.maxQueueSize | int |
max queue length in frames; only used if queueModule=="" |
|
mac.bitrate | double | ||
mac.rtsThresholdBytes | int | 2346B |
longer messages will be sent using RTS/CTS |
mac.retryLimit | int | -1 |
maximum number of retries per message, -1 means default |
mac.cwMinData | int | -1 |
contention window for normal data frames, -1 means default |
mac.cwMinBroadcast | int | -1 |
contention window for broadcast messages, -1 means default |
mac.mtu | int | 1500 | |
radio.channelNumber | int | 0 |
channel identifier |
radio.transmitterPower | double | 20mW |
power used for transmission of messages (in mW) |
radio.bitrate | double |
(in bits/s) |
|
radio.thermalNoise | double | -110dBm |
base noise level (dBm) |
radio.pathLossAlpha | double | 2 |
used by the path loss calculation |
radio.shadowingDeviation | double | 0dB |
used by the shadowing model calculation |
radio.snirThreshold | double | 4dB |
if signal-noise ratio is below this threshold, frame is considered noise (in dB) |
radio.sensitivity | double |
received signals with power below sensitivity are ignored |
