Sim.Routing.DSR
Class DSRRoutingAlgorithm

java.lang.Object
  Sim.Routing.AbstractRoutingAlgorithm
      Sim.Routing.DSR.DSRRoutingAlgorithm

All Implemented Interfaces:

RoutingAlgorithm

public class DSRRoutingAlgorithm
extends AbstractRoutingAlgorithm

DSRRoutingAlgorithm implements most of the DSR protocol.

Constructor Summary

DSRRoutingAlgorithm()

Method Summary

void	arrived(HardwareFrame in) Event when a HardwareFrame arrives destined for this Node that does not have a user Packet, or has a Packet not for this Node.
static void	enableLog(boolean enabled) Set to true to enable logging of a lot of debugging information to standard output.
void	newPacket(Node dest, Packet packet) Event when a Node wants to send a new Packet.
void	overheard(HardwareFrame in) Event when a HardwareFrame is overheard by a Node (the HardwareFrame's destination is not the Node).
void	terminated(HardwareFrame in) Event when a HardwareFrame arrives destined for this Node that has a user Packet that is destined for this Node.

Method Detail

enableLog

public static void enableLog(boolean enabled)

Set to true to enable logging of a lot of debugging information to standard output.

arrived

public void arrived(HardwareFrame in)

Event when a HardwareFrame arrives destined for this Node that does not have a user Packet, or has a Packet not for this Node. The data in the frame may need to be routed.

Specified by:

arrived in interface RoutingAlgorithm

Overrides:

arrived in class AbstractRoutingAlgorithm

Parameters:

in - non-null HardwareFrame received

terminated

public void terminated(HardwareFrame in)

Event when a HardwareFrame arrives destined for this Node that has a user Packet that is destined for this Node. The data has arrived at its final destination, so it does not need to be routed.

Specified by:

terminated in interface RoutingAlgorithm

Overrides:

terminated in class AbstractRoutingAlgorithm

Parameters:

in - non-null HardwareFrame received

newPacket

public void newPacket(Node dest,
                      Packet packet)

Event when a Node wants to send a new Packet. The RoutingAlgorithm should bundle the Packet in a HardwareFrame and send it through the Node.

Specified by:

newPacket in interface RoutingAlgorithm

Overrides:

newPacket in class AbstractRoutingAlgorithm

Parameters:

dest - non-null Node as the destination (packet.getDest() == dest.getAddress())

packet - user packet data to send, with a destination address not equal to the address for the sending Node.

overheard

public void overheard(HardwareFrame in)

Event when a HardwareFrame is overheard by a Node (the HardwareFrame's destination is not the Node).

For DSR, this checks for passive acknowledgement

Specified by:

overheard in interface RoutingAlgorithm

Overrides:

overheard in class AbstractRoutingAlgorithm

Parameters:

in - non-null HardwareFrame received
