Class CBR

java.lang.Object
  driver.CBR

public class CBR
extends java.lang.Object

Constant Bit Rate simulation program. This program creates a field and places nodes randomly throughout it. Some of the nodes are designated as client-server pairs, and these pairs transmit packets to each other for the duration of the simulation. It is possible to specify, among other things, the routing protocol used, the packet loss probability, and the rate of node movement.
