Performance Analysis of Modified IEEE 802.11-Based Cognitive Radio Networks


This letter considers a modified IEEE 802.11-based cognitive radio network where primary users (PUs) operate on a slot-by-slot basis and secondary users (SUs) try to exploit the time unused by primary users (PUs). To improve the throughput for SUs, our IEEE 802.11-based opportunistic spectrum access (OSA) allows SUs to transmit packets with variable length… (More)
