Lecture 1-2:  Cluster-based Cooperative Spectrum Sensing in Cognitive Radio Networks (CRNs)

Intro: Cognitive radio (CR) networks have been active area of research because of its ability to opportunistically share the spectrum. A cluster-based cooperative spectrum sensing (CCSS) has a tremendous impact on sensing reliability compared with cooperative spectrum sensing. The energy detection (ED) technique requires perfect knowledge of noise power. An eigenvalue-based spectrum sensing has mitigated the noise uncertainty problem. Sensing and reporting time slots are rigidly separated in the conventional ED and eigenvalue-based detection (EVD) schemes. In CCSS, more reporting time slots are required as the number of CR users (CRUs) increases. If the reporting time slots of other CRUs as sensing time slots with a superposition allocation, the more reliable channel sensing can be achieved. In this paper, we propose CCSS using EVD technique with a superposition approach scheme where the reporting time slot is properly utilized to sense the primary user's (PU's) signal more accurately by rescheduling the reporting time slot for CRUs and cluster heads (CHs). Simulation result shows that the proposed EVD scheme has better detection probability than the conventional CCSS using both ED and EVD techniques.

 

Lecture 3-4:  Sensing and Throughput Analysis of a MU-MIMO based Cognitive Radio-based Internet of Things (CR-IoT)

Intro: State-of-the-art energy detection (ED) based spectrum sensing requires perfect knowledge of noise power and is vulnerable to noise uncertainty. An eigenvalue-based spectrum sensing approach performs well in such an uncertain environment, but does not mitigate the spectrum scarcity problem, which evolves with the future Internet of Things (IoT) rollout. In this paper, we propose a multi-user multiple-input and multiple-output (MU-MIMO) based cognitive radio scheme for the Internet of Things (CR-IoT) with weighted-eigenvalue detection (WEVD) for the analysis of sensing, system throughput, energy efficiency and expected lifetime. In this scheme, each CR-IoT user is being equipped with MIMO antennas; we calculate the WEVD ratio, which is defined as the ratio between the difference of the maximum eigenvalue and minimum eigenvalue to the sum of the maximum eigenvalue and minimum eigenvalue. This mitigates against the spectrum scarcity problem, enhances system throughput, improves energy efficiency, prolongs expected lifetime and lowers error probability. Simulation results confirm the effectiveness of the proposed scheme; here the WEVD technique demonstrates a better detection gain and enhanced system throughput in comparison to the conventional scheme with eigenvalue based detection (EVD) and ED techniques in a noise uncertainty environment (i.e. SNR <-28). Furthermore, the proposed scheme has lower energy consumption, prolonged expected lifetime and achieves a low error probability when compared with other schemes like the conventional single-input and single-output (SISO) based CR-IoT scheme with EVD and ED spectrum sensing.

 

Lecture 5-6:  Energy Harvesting-enabled Cognitive Radio-Internet of Things (CR-IoT) using Machine Learning

Intro: The cognitive radio (CR) is a modern technology in cognitive radio-Internet of things (CR-IoT) networks. In contrast, each CR-IoT user is unable to achieve both a better sensing gain, and an enhanced system sum rate in conventional energy detection technique based CR-IoT networks with the present energy harvesting (EH) and security threats due to under-utilized the reporting framework. For this reason, we proposed EH-enabled CR-IoT networks using machine learning (ML) algorithms in which each normal CR-IoT user is assisted by finite capacity battery systems and energy harvested. In this paper, Firstly, the proposed hybrid detection technique based on EH-enabled CR-IoT networks using ML algorithms is separating the trusted (normal) and untrusted (malicious users) CR-IoT users where all untrusted CR-IoT users are not participating in spectrum sensing due to they degraded the performance like sensing gain and system sum rate; Secondly, the proposed scheme is utilized the reporting framework where only trusted CR-IoT users are obtained longer sensing time slot which enhanced the sensing gain, the EH, and the sum rate; and Finally, the simulation results show that the proposed hybrid scheme outperformed the conventional schemes in terms of security, sensing gain, EH, and system sum rate.

 

Lecture 7-8:  MU-MIMO Based Spectrum Sensing and Sum Rate in a Cognitive Radio for Internet of Vehicular Things

Intro: Cognitive radio CR is applied to vehicular ad-hoc networks (VANETs) which is utilized the unused licensed spectrum more efficiently. However, the vehicles in the CR-VANETs era are constrained regarding spectrum, sum rate, energy consumption, error probability, and antenna size to meet the demands, resulting in a growing number of interconnected vehicles for Internet of things (IoT) networks. To overcome these constrained in IoT networks that is needed a revision of the IoT architecture for the Internet of vehicular things (IoVT). In this article, we present a multi-user multiple-input and multiple-output (MU-MIMO) antennas aided cooperative spectrum sensing (CSS) for a CR based IoVT (CR-IoVT) network where firstly, each cognitive radio vehicle (CRV) is assumed to be equipped with MIMO antennas; secondly, the detection gain of the secondary network i.e., (CR-IoVT) is measured based on the energy detection method; and finally, the fusion center makes a global decision about the status of the  primary user signal in a CR-IoVT network by applying the soft data fusion rules i.e., equal gain combining (EGC) and maximal ratio combining (MRC) rules. Simulation results are presented to demonstrate that the proposed scheme achieves an improved detection gain, an enhanced sum rate, and a fewer error probability when compared to other conventional schemes like the non-CSS (NCSS) scheme with a single-input and single-output (SISO) antenna and CSS scheme with a SISO antenna.
