This thesis proposes a method of using the <strong>physical</strong> <strong>layer</strong> signal from a collision<br />
<strong>to</strong> detect the existence of a weak <strong>tag</strong> in the presence of stronger <strong>tag</strong> <strong>to</strong> <strong>improve</strong> the<br />
reliability of the present pro<strong>to</strong>col. The performance of random number genera<strong>to</strong>r on<br />
the chip and may be non-ideal leading <strong>to</strong> a non-uniform distribution. The effect of<br />
this deviation from the theoretical values and its effect on the performance of the<br />
pro<strong>to</strong>col is analyzed by simulation. Output of the random number genera<strong>to</strong>r of some<br />
standard RFID <strong>tag</strong>s is also evaluated.<br />
