TOKEN RING SIMULATOR Download
When You click GO button you can
run simulator with a created Nodefile.
Nodefile includes the simulation
environment which need to be a input for the simulator.
When you click to WIZARD button
you can create Nodefiles
NEXT button in WTRS Environment
is pass you to the program that creates nodes.
Node address should be 6
character long and you can choose the node movement pattern and X and Y
locations are optional . If the X and Y locations are not selected than
the program uniformly distributes the initial location. You can stop node
creation by clicking GO button or continue with Next Node button. You can see
the Nodefile by clicking Show File Button.
After you create the nodes you
can attach CBR traffic agents . One node can be assigned more than one
agent. If you want to stop or do not want then traffic Pass CBR button
run the simulator by canceling agent attachment.
WTRS runner shows the simulation
time and you can stop and re-start the simulation . In order to quit the
program Stop button must be used .
Stop Button run the .nam file
that the program created, in
can see the node movements
, transmissions ,receptions and ring address of each node.
Transmissions is represented by
a red square and reception is transmitted as a green circle. node ids are
written in the black circle and ring address is written at the top of the black
circle. Click for a simulation
If you click to ANALYZE button
on main program you can analyze the, .tr file that the program created,
This graph shows two scenarios
in the red one 10 node in the medium is stable and graph shows that it forms
the ring and remains 10 node. Second one , green line, is for the
scenario in which 9 nodes are stable and 1 node is moving (when it reaches the
boundary of the topology it bounces back and continues.) Green one represent
that protocol robust against single node failures. when the node left protol
recover the ring.
