Aloha MAC protocol

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.

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.

P2PNic

The nic (network interface card) is a compound module that contains the MAC and PHY of a host within the Mobility Framework
AlohaSnrNic

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

The nic (network interface card) is a compound module that contains the MAC and PHY of a host within the Mobility Framework

Parameters:

Name Type Description
debug bool

debug switch
headerLength numeric const

level at which we consider medium busy
queueLength numeric const

length of the MAC queue
bitrate numeric const

bit rate in bit/s
defaultChannel numeric const

default channel

Gates:

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

for control messages to upper layer
lowerControlIn input

for control messages from phy layer
