Cognitive Radio Impact on Radio Astronomy

The introduction of new communication techniques requires an increase in the efficiency of spectrum usage. Cognitive radio is one of the new techniques that foster spectrum efficiency by using an unoccupied frequency spectrum for communications. However, cognitive radio will increase the transmission power density and cause an increased level of Radio Frequency Interference (RFI), which may impact other services and particularly passive users of the spectrum. In this paper, we present the principles of cognitive radio and introduce a model for its impact on radio astronomy.

The cognitive radio of NASA builds upon the infrastructure being developed by STRS (Space Telecommunication Radio System) SDR technology. The architecture of STRS describes techniques that can notify the cognitive engine regarding the radio surroundings so that the cognitive engine can separately learn from experience & take suitable actions to adapt the radio operating characteristics & enhance performance.

Energy-Aware Cognitive Radio Systems

The concept of energy-aware communication has encouraged the research community interest in the most current years because of different economical & environmental reasons. For wireless communication systems, it becomes essential to move their resource allocation troubles from optimizing fixed metrics like latency & throughput.

A literature study of current resource allocation methods based on energy-efficient is presented for cognitive radio systems. So these methods’ energy efficiency performances are analyzed & evaluated in power budget, adjacent-channel & co-channel interferences, quality-of-service, channel estimation errors, etc.

Listen & talk full-duplex CRN

The use of full-duplex radio within cognitive radio networks presents a novel spectrum-sharing protocol to allow the secondary users to sense & access the vacant spectrum simultaneously. Protocol like LAT (listen & talk) is assessed through both mathematical analysis & computer simulations as compared to other access protocols like the listen-before-talk protocol. In addition to signal processing based on LAT & resource allocation, it discusses methods like spectrum sensing & dynamic spectrum access. It proposes LAT protocol as an appropriate access system for CRNs for supporting the quality-of-service requirements of high-priority applications.

Radio Systems Adaptation with Hybrid Cognitive Engine

Network efficiency & its resource’s proper utilization are crucial requirements for operating wireless n/ws optimally. Cognitive radio targets perform these requirements by developing artificial intelligence (AI) methods to make an entity known as a cognitive engine.

The cognitive engine develops awareness regarding the nearby radio environment to optimize the utilization of radio resources & adapt related transmission parameters. Here, a hybrid cognitive engine is proposed that employs CBR (Case-Based Reasoning) & DTs (Decision Trees) to execute radio adaptation within multi-carrier wireless n/s. The complexity of the engine is decreased by employing decision trees to enhance the indexing method utilized in CBR case retrieval.

Sharing of Distributed Opportunistic Spectrum in CRN

Whenever the licensed radio spectrum is underutilized then cognitive radio technology allows cognitive devices simply for detecting & after that access this scarce resource dynamically. Here, a simple, instinctive, efficient, and yet powerful method allows opportunistic channels within cognitive radio systems in a distributed manner.

This proposed technique attains extremely high spectrum utilization & throughput value. And, it also reduces interference between cognitive base stations & the main licensed users to utilize the spectrum. The algorithm quickly & efficiently reacts to differences within the parameters of the network & also attains a high amount of fairness among cognitive base stations.

Defense Mechanism Design to Mitigate the Spectrum Sensing Data Falsification Attack within Cognitive Radio Ad Hoc Networks

Cognitive radio networks address the spectrum scarcity problem by allowing simply unlicensed users called secondary users to use the licensed user’s unused spectrum band called primary users without causing intrusion to the primary users. However, this results in some safety challenges where malicious secondary users report wrong spectrum observations which are known as the SSDF (spectrum sensing data falsification) attack. Here, we study the SSDF attack within a cognitive radio ad hoc network. So the reputation & the q-out-of-m rule schemes are integrated to lessen the SSDF attack effects.
