Simple Module ChannelControl

File: World/ChannelControl.ned

C++ definition: click here

ChannelControl has exactly one instance in every network model that contains mobile or wireless nodes. This module gets informed about the location and movement of nodes, and determines which nodes are within communication or interference distance. This info is then used by the radio interfaces of nodes at transmissions.

Side effect: updates the containing compound module's display string according to the given playground size (sets "p=0,0;b=$playgroundSizeX, $playgroundSizeY").

This ChannelControl is a different implementation from the one in Mobility Framework 1.0a5: here we use sendDirect(), while the MF version used normal send() and dynamic connections.

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.

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.
