“…The limit less need of the radio spectrum is thus one of the most urgent issues at the forefront of future network research that has yet to be addressed. One solution to these and other challenges is to use cognitive radio technology, which has undergone extensive investigation by the research community for almost two decades [2][3][4].…”

Cognitive radio is an intelligent network which addresses the availability of radio spectrum in order to enable dynamic spectrum access. This paper is based on engineering model for electromagnetic spectrum, which deals with current scarcity-based regulatory model. It is an intelligent platform through which static frequency allocations can done to dynamic, intelligent, and instantaneous frequency negotiations and assignment. Various detection models were discussed to make the radio spectrum abundance model possible, and a brief discussion on the architecture of mobile network. It was identified as a promising solution to the limit less need of spectrum and the main idea behind is for dynamic access of unused spectrum for communication. Its play a vital role for dynamic utilization of idle spectrum without affecting the rights of primary users, so that the services can be available for different or for other services. In this unused spectrum can be share in order to achieve a prominent goal for avoiding the cost of usage of spectrum. It also helps in improving the utilization of spectrum resources. In order to meet the critical requirements of the fifth generation (5G) mobile network, especially the Wider-Coverage, Massive-Capacity, Massive-Connectivity, and Low-Latency four application scenarios, the spectrum range used in 5G will be further expanded into the full spectrum era, possibly from 3 GHz to 300 GHz.

“…Diversified spectrum sharing patterns (e.g. ISM bands and TV white spaces [2], cellular network and satellite system [3], LSA bands and unlicensed bands [4]) require full awareness of electromagnetic situation, including the current situation and future trends of electromagnetic environment, so as to achieve accurate and reliable customization of spectrum sharing strategies. Spectrum sharing strategy, known as the transmission information in time, frequency, spatial and energy domain [5], largely depends on the full knowledge of local electromagnetic environment, which further depends on spectrum sensing and spectrum-sensing-based spectrum inference.…”

To achieve secure and immutable spectrum data monitoring and sharing, and further to realize accurate and reliable spectrum strategy customization, a mobile edge computing (MEC) enabled spectrum blockchain is developed for the internet of spectrum devices (IoSD). Specially, a three-stage consensus mechanism is designed to achieve secure and immutable spectrum data monitoring and sharing, and spectrum blockchain employs the edge-deployed personal wireless device to realize efficient storage of massive spectrum data and quickly response of spectrum strategy customization. The malicious behaviour of spectrum data falsification is employed as Byzantine attack to evaluate the security performance of the proposed MEC-enabled spectrum blockchain. Numerical simulations show the consensus mechanism identify the malicious behaviours with high probability of detection under a variety of scenarios.

“…It plays an important role in many fields of research, e.g., Internet of Things [ 15 ], cellular mobile communication [ 16 ], WiMAX [ 17 ], wireless sensor network [ 18 ], aeronautical communication [ 19 ], ad hoc network [ 20 ] and satellite communication [ 21 ]. In addition, many cognitive technologies are presented, e.g., spectrum sensing [ 22 , 23 , 24 , 25 ], smart antennas and beamforming [ 26 , 27 , 28 ], beacon signaling [ 25 , 29 ], interference alignment [ 30 , 31 , 32 ], precoding [ 33 ], power control [ 34 , 35 , 36 , 37 , 38 ], beamhopping [ 39 , 40 ] and network coding [ 41 ].…”

“…Although cognitive radio in terrestrial wireless systems has been deeply studied, the usage in satellite communications faces new challenges, e.g., system architecture, propagation model, round-trip delay, receiver characteristics, satellite characteristics, broad beam coverage, power level and limited possibilities of evolution due to the long system development and the fixed design space segment [ 37 ]. There are many open avenues to exploit cognitive radio in satellite communications, especially for the dual satellite network, in which the spectrum is shared between two satellite systems.…”

“…Nevertheless, it is well known that adjusting the satellite attitude results in the consumption of fuel whether the propulsion is powered electrically or chemically, which will shorten the lifetime of the satellite. Reference [ 37 ] reviewed the database approach and pointed out that the awareness of other systems’ operational characteristics, such as frequency allocations, orbital positions, and antenna patterns, is the key for the successful coexistence between NGSO satellite systems. In this regard, Reference [ 38 ] proposed an Adaptive Power Control (APC) technique to ensure the spectral coexistence between the GEO and NGSO satellites.…”

A Novel Dynamic Spectrum-Sharing Method for Integrated Wireless Multimedia Sensors and Cognitive Satellite Networks

With the growing demand, Wireless Multimedia Sensor Networks (WMSNs) play an increasingly important role, which enhances the capacity of typical Wireless Sensor Networks (WSNs). Additionally, integrating satellite systems into WMSNs brings about the beneficial synergy, especially in rural and sparsely populated areas. However, the available spectrum resource is scarce, which contradicts the high-speed content required for multimedia. Cognitive radio is a promising solution to address the conflict. In this context, we propose a novel spectrum-sharing method for the integrated wireless multimedia sensor and cognitive satellite network based on the dynamic frequency allocation. Specifically, the Low Earth Orbit (LEO) satellite system plays the role of the auxiliary to connect sensor nodes and the remote control host, and it shares the same frequency with the Geostationary Earth Orbit (GEO) system in the downlink. Because the altitudes of GEO and LEO satellites differ greatly, the beam size of GEO is much larger than that of LEO, which provides the opportunity for LEO beam to reuse the frequency that was allocated to the GEO beam. A keep-out region is defined to guarantee the spectral coexistence based on the interference analysis in the worst case. In addition, a dynamic frequency allocation algorithm is presented to deal with the dynamic configuration caused by the satellite motion. Numerical results demonstrate that the dynamic spectrum-sharing method can improve the throughput.
