Efficient spectrum utilization.
Figure 19 Subcarrier reuse leading to efficient spectrum utilization.
Efficient spectrum utilization is one of the main research points in 5G.
In traditional wireless networks, efficient spectrum allocation and access scheduling can significantly improve the network performance.
Thus, efficient spectrum mobility procedure should be considered when designing the routing protocols for CRAHNs.
The increasing demand for wireless communication presents a challenge to have an efficient spectrum use.
This is also due to the more efficient spectrum sharing at higher interference TxRates.
Therefore, low complexity, energy efficient spectrum sensing algorithms are vital for implementation in such devices.
To achieve efficient spectrum utilization, cognitive radio requires a robust spectrum sensing and spectrum sharing scheme.
In this paper, we propose an efficient spectrum sensing scheme for a distributed CRN MAC.
The increasing demand for wireless communication presents an efficient spectrum utilization challenge.
