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.
This module supports ad-hoc mode only (does not generate or handle management frames), and does not support fragmentation, RTS threshold, duplication detection and recovery.
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.
If a module type shows up more than once, that means it has been defined in more than one NED file.
