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.

NicCsma (compound module)

The CsmaNic contains a csma-like MAC layer. The SnrEval module is used as the mac needs a RadioState to be published. However as still the BasicDecider is used all messages will be delivered to the MAC and no packets get lost

SnrNic (compound module)

This is the easiest nic to implement "real" network behaviour. It uses the CsmaMacLayer and the SnrDecider and SnrEval modules.

Parameters:

Name Type Default value Description
debug bool false

debug switch

headerLength int
queueLength int

Properties:

Name Value Description
display i=prot2

Gates:

Name Direction Size Description
uppergateIn input
uppergateOut output
lowergateIn input
lowergateOut output
