Adaptive se<strong>ns</strong>ing (Algorithm C)<br />
• In case of a collision:<br />
– All idle CPEs per<strong>for</strong>m fine se<strong>ns</strong>ing at the slots collision<br />
occurred<br />
– Attacker must be detected from all CPEs per<strong>for</strong>ming<br />
the se<strong>ns</strong>ing.<br />
– After detection cell begi<strong>ns</strong> the channel change<br />
process.<br />
• Energy co<strong>ns</strong>umption is an important factor.<br />
– Se<strong>ns</strong>ing cannot be per<strong>for</strong>med in infinite time<br />
– Energy loss due to se<strong>ns</strong>ing shouldn’t override energy<br />
loss caused by interference.<br />
