Abstract EN
In a cognitive radio network (CRN), the number of spectrum handoffs increases energy consumption of cognitive (or secondary) users due to the channel switching process.
This might limit the operation of the CRN, especially in scenarios where secondary users terminals are battery-powered.
Thus, reducing the number of times a cognitive user involved in a transmission switch to different spectrum holes is required to increase battery life-time.
In this regard, available spectrum holes possess different attributes (e.g., bandwidth) that can be exploited to satisfy specific secondary users requirements (i.e., connection profile) for data transmission while saving energy.
Here, three multiple attribute decision-making (MADM) algorithms for the spectrum decision functionality are evaluated using real spectrum measurements of TV bands.
This is performed by proposing six decision parameters, which are extracted from the spectrum data to characterize its suitability.
Then, these are used as inputs of the MADM algorithms to select the most suitable spectrum hole for a cognitive user.
Thus, an enhanced MADM-based decision process is proposed to reduce the number of handoffs considering energy consumption due to channel switching (ECCS).
Results quantify savings from 30% to 90% in ECCS and spectrum handoffs reductions from 47% to 90%.
