Compound Module P2PNic

File: contrib/nic/P2PNic.ned

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

The P2P nic only contains a simple phy layer which provides no snr evaluation but simple sends unicast messages and calculates the bit errors based on a bit error probability provided in omnetpp.ini

IMPORTANT:
In order to work with our ChannelControl module the phy module has to be called "phy" in the ned file.

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.

AlohaMacLayer	Aloha MAC protocol
P2PPhyLayer	A very simple physical layer
SingleChannelRadio	(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.

P2PHost

The P2PHost is a compound module that implements a very simple peer to peer host. Instead of an "snrEval" and "decider" module it just contains a simple "phy" module that sends unicast messages

Gates:

Name	Direction	Description
uppergateIn	input	to upper layers
upperControlOut	output	control to upper layers
uppergateOut	output	from upper layers
radioIn	input	gate for sendDirect

Unassigned submodule parameters:

Name	Type	Description
mac.debug	bool	debug switch
mac.headerLength	numeric const	level at which we consider medium busy
mac.queueLength	numeric const	length of the MAC queue
mac.bitrate	numeric const	bit rate in bit/s
mac.defaultChannel	numeric const	default channel
phy.coreDebug	numeric const	debug switch for the core framework
phy.pBit	numeric const	bit error rate
phy.bitrate	numeric const	bitrate (in bits/sec)
phy.transmitterPower	numeric const	power used to transmit messages (in mW)
phy.headerLength	numeric const	length (in bits) of the AirFrame header
radio.debug	bool
radio.swSleep	numeric const	time parameters, how long does it take to switch to sleep mode
radio.swSend	numeric const	switch to send mode
radio.swRecv	numeric const	switch to recv mode
