Benchmarking of Algorithms to Forecast Spectrum Occupancy by Primary Users in Wireless Networks
García Hernández, Diego Giral, Fredy Martínez · International Journal of Engineering and Technology · 2018
One of the most relevant aspects in the performance of wireless cognitive communications is the interference between users, especially the one that the secondary user can cause to the primary user.A proactive handoff strategy considerably reduces said interference.However, highly accurate prediction models are required.The following article seeks to compare the performance of four algorithms in the spectral occupancy of the primary user during a secondary user's communication.The performance of the algorithms is assessed by using five metrics: handoffs, failed handoffs, bandwidth, delay and throughput.The simulation scenario involves the communication of a secondary user during 10 minutes in a Wi-Fi network.
