Spectrum sensing allows cognitive radio systems to detect relevant signals even in the presence of interference for reliable communication. Most of the existing spectrum sensing techniques use a particular signal‐to‐noise ratio model with assumptions and provide certain detection performance. Dynamic spectrum management techniques enabled the efficient allocation of channels to increasing number of users. In cognitive radio system, the dynamic spectrum management is efficient for sensing the channel occupancy and mobilizing the secondary user towards the unused primary user channel. For spectrum sensing, wavelet‐based spectrum sensing method is analyzed and effectively made spectrum decision. The performance analysis is made for various SNR values with enhanced false alarm and throughput in spectrum management cognitive radio system in 2.2 GHZ band communication.

Drones provide an alternative progression in protection submissions since they are capable of conducting autonomous seismic investigations. Recent advancement in unmanned aerial vehicle (UAV) communication is an internet of a drone combined with 5G networks. Because of the quick utilization of rapidly progressed registering frameworks besides 5G officialdoms, the information from the user is consistently refreshed and pooled. Thus, safety or confidentiality is vital among clients, and a proficient substantiation methodology utilizing a vigorous sanctuary key. Conventional procedures ensure a few restrictions however taking care of the assault arrangements in information transmission over the internet of drones (IOD) environmental frameworks. A unique hyper elliptical curve (HEC) cryptographically based validation system is proposed to provide protected data facilities among drones. The proposed method has been compared with the existing methods in terms of packet loss rate, computational cost, and delay and thereby provides better insight into efficient and secure communication. Finally, the simulation results show that our strategy is efficient in both computation and communication.

This study examines the mechanical characteristics of a novel hybrid composite consisting of 25% ramie fiber, 15% kenaf fiber, and 2% titanium dioxide particles. Ramie fiber is known for its tensile rigidity and durability, while kenaf fiber is valued for its availability and biodegradability. Titanium dioxide particles are included to enhance the composite's mechanical properties. Mechanical tests—including tensile, bending, impact, and hardness—were conducted, revealing an average tensile strength of 66.14 MPa, a flexural strength of 86.46 MPa, an impact strength of 35.88 kJ/m2, and a hardness of 181.8 HV. The significance of this study lies in its innovative combination of natural fibers with inorganic particles, addressing the demand for high-performing yet eco-friendly materials. The novelty of the composite is reflected in the strategic integration of ramie and kenaf fibers, which offer complementary mechanical properties, with titanium dioxide particles to enhance overall performance. This approach achieves a balance between strength, rigidity, and impact resistance while maintaining environmental sustainability. The inclusion of titanium dioxide boosts mechanical performance without compromising the material's eco-friendly nature. These findings suggest that this composite is suitable for technical applications requiring exceptional strength, rigidity, and impact resistance. This research contributes to the advancement of composite materials technology, showing potential for the development of sustainable and effective materials across various industries.
