Usage diagram:

The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.

Contains the following modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

Decider80211

Decider module of the 802.11 modules

Mac80211

Implementation of the 802.11b MAC protocol. This module is intended to be used in combination with the SnrEval80211 and Decider80211 modules as physical layer.

SnrEval80211 (no description)

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

MobileHost

Models a mobile host with a wireless (802.11b) card. This module is a WirelessHost less the PPP and Ethernet interfaces, plus mobility support (BasicMobility). It is intended mainly for mobile ad-hoc networks.

WirelessHost2

Models a host with zero, one or more wireless (802.11b) cards. This module is a variation of WirelessHost.

WirelessHost

Models a host with one wireless (802.11b) card. This module is basically a StandardHost with a Nic80211 added.
