Spectrum mobility in cognitive radio networks not only enables the secondary users to
guarantee the desired QoS of the primary users but also grants an efficient exploitation of …

Frame aggregation (FA) mechanisms improve the throughput of WLANs. In this paper, the
effect of the FA mechanism on the throughput of wireless local area networks (WLANs) has …

In this paper, we analyze the saturation throughput of a cognitive WLAN overlaid on a
primary OFDMA TDD network (eg, LTE or WiMAX). In this scenario, after the contention …

This dissertation considers gray-space primary-secondary spectrum sharing, in which
secondary devices are allowed to transmit when primary transmissions are strong enough …

In this paper, we focus on a cognitive network scenario, comprised of a WLAN overlaid on a
network with time-scheduled primary users. WiMAX is an example of such primary networks …

In this paper, we focus on a cognitive network scenario, comprised of a multi-hop IEEE
802.11-based WLAN overlaid on a cellular network. In this scenario, the wireless nodes in a …

In this study, the authors propose an analytical model to evaluate the maximum stable
throughput and average delay of a cognitive IEEE 802.11-based wireless local area network …

This paper analyzes the saturation throughput of a cognitive single hop WLAN overlaid on a
primary IEEE 802.16 e TDD WiMAX network. After the contention among the secondary …

In this paper, we propose a new scenario in order to increase the total throughput of a
WLAN. In this scenario, some secondary users (SUs) are considered in a primary WLAN …
