Compound Module P2PHost

File: networks/p2p/P2PHost.ned

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

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.

BasicApplLayer

Basic class for the application layer

BasicMobility

Basic module for all mobility modules.

Blackboard

The Blackboard works as entity to enable inter layer / process communication.

P2PNic

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

SimpleArp (no description)
SimpleNetwLayer

Basic class for the network layer

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.

P2PNetwork

A network only consisting of basic modules
