Class InterferenceLimitedInterface

java.lang.Object
  core.NetworkInterface
      interfaces.InterferenceLimitedInterface

All Implemented Interfaces:

ModuleCommunicationListener

public class InterferenceLimitedInterface
extends NetworkInterface

A simple Network Interface that provides a variable bit-rate service, where the bit-rate depends on the number of other transmitting stations within range The current transmit speed is updated only if there are ongoing transmissions. The configured transmit speed is the maximum obtainable speed.

InterferenceLimitedInterface

public InterferenceLimitedInterface(InterferenceLimitedInterface ni)

Copy constructor

Parameters:

ni - the copied network interface object

Method Detail

replicate

public NetworkInterface replicate()

Description copied from class: NetworkInterface

Replication function

Specified by:

replicate in class NetworkInterface

getTransmitSpeed

public int getTransmitSpeed()

Returns the transmit speed of this network layer

Overrides:

getTransmitSpeed in class NetworkInterface

Returns:

the transmit speed

connect

public void connect(NetworkInterface anotherInterface)

Tries to connect this host to another host. The other host must be active and within range of this host for the connection to succeed.

Specified by:

connect in class NetworkInterface

Parameters:

anotherInterface - The host to connect to

update

public void update()

Updates the state of current connections (i.e., tears down connections that are out of range).

Specified by:

update in class NetworkInterface

createConnection

public void createConnection(NetworkInterface anotherInterface)

Creates a connection to another host. This method does not do any checks on whether the other node is in range or active

Specified by:

createConnection in class NetworkInterface

Parameters:

anotherInterface - The interface to create the connection to

isTransferring

public boolean isTransferring()

Returns true if this interface is actually transmitting data

toString

public java.lang.String toString()

Returns a string representation of the object.

Overrides:

toString in class NetworkInterface

Returns:

a string representation of the object.
