Dynamic Spectrum Handovers in Cognitive Radio Networks
Wireless systems, spectrum handover, and radio networks have experienced a drastic transition due to modern-day technological initiatives. This advancement is evident in the static spectrum, which is a feasible resolution to the dynamic status of wireless networks and necessitates the reassurance of networking alternatives related to spectrum handovers. Cognitive networks are efficient and most effective initiative to ensuring dynamic spectrum handovers that will exploit the usage of spectrum handover are distributed to other neighboring potential devices. The application of the Cognitive Radio (CR) and its capabilities signals the nodes, which are unrestrained to the usage of static spectrum, other than selecting it based on its ultimatum. Conversely, the utility of dynamic spectrum leads to some problems that have to be discussed in further details: effective apportionment of the spectrum between CR users and licensed users aimed at maximizing the usage of the spectrum. The second problem is the avoidance of interferences with devices’ levels. Hence, this paper critically analyzes the dynamic spectrum handovers in cognitive networks by analyzing previous literature first. By evaluating diverse dynamic spectrum schemes and models, this research includes a discussion of problems and proposition of novel resolutions for the allocation of spectrums applying the multi-agent systems. The results of simulation indicate that this mitigating factor signifies approximately 80% of spectrum usages in a few message spans hence providing a fundamental mechanism for the handover of the dynamic spectrum.
