Constructor Detail

RFIDSim

public RFIDSim(int nTags,
               double BER,
               double bw,
               int simTime)

Constructs the reader

Method Detail

inventory

public int[] inventory()

Causes reader to start its inventorying process.

Returns an array of counts of the number of frames of each type sent. (The types are defined by the FrameType enum in RFIDFrame.java.)

main

public static void main(java.lang.String[] args)

This main runs the show.

Command line args, in order:

• number of iterations to run
• number of tags per run
• bit error rate (e.g., .0001)
• bandwidth, in bps (e.g., 100000)
• maximum inventorying time (in msec.)

A sample invocation might look like this:

java -cp . sim/RFIDSim 3000 20 .01 100000 1000
