چکیده
This letter proposes a higher order moments-based spectrum sensing method for detecting unauthorized accesses in underlay cognitive satellite communication networks. Exploiting the second, fourth and sixth-order moments of received signal, an estimate hidden signal power is evaluated. Then, estimation user used as decision variable to distinguish among presence or absence transmission within network. The effectiveness proposed algorithm assessed by simulation. analyses have shown that it overcomes some recently published techniques failing users communications.

Robust Detection of Unauthorized Wireless Access Points
Unauthorized 802.11 wireless access points (APs), or rogue APs, such as those brought into a corporate campus by employees, pose a security threat as they may be poorly managed or insufficiently secured. An attacker in the vicinity may easily get onto the internal network through a rogue AP, bypassing all perimeter security measures. Existing detection solutions do not work well for detecting r...
متن کاملDetecting and Blocking Unauthorized Access in Wi-Fi Networks
Academic and commercial 802.11 hotspots often use an SSLsecured captive portal to authenticate clients. Captive portals provide good usability and interoperability, but poor security. After a captive portal has authenticated a client, session hijacking and freeloading allow attackers to capture or use the client’s session. Freeloading does not require special tools and, surprisingly, is strengt...
متن کاملFull-Duplex Relay Selection in Cognitive Underlay Networks
In this work, we analyze the performance of fullduplex relay selection (FDRS) in spectrum-sharing networks. Contrary to half-duplex relaying, full-duplex relaying (FDR) enables simultaneous listening/forwarding at the secondary relay(s), thereby allowing for a higher spectral efficiency. However, since the source and relay simultaneously transmit in FDR, their superimposed signal at the primary...
متن کاملRobust Power Control for Cognitive Radio in Spectrum Underlay Networks
Power control is a key technique in spectrum underlay cognitive network to guarantee the interference temperature limit of the primary users (PUs) and the quality of service of the secondary users (SUs). In this paper, a robust power control scheme via link gain pricing with H∞ estimator is proposed. The scheme guarantees the interference temperature of the PUs through operating in the network-...
متن کاملSpatial interference shaping for underlay MIMO cognitive networks
Interference temperature (IT) is a widely-used approach for protecting primary users (PUs) from the secondary users (SUs) in underlay cognitive radio. However, when multiple antennas are available at the transmitters and receivers, the spatial structure of the interference comes into play, strongly affecting the performance of the primary network. In this work, we propose interference shaping c...
