Abstract:
Depending on the targeted wireless application, a collaborative spectrum allocation strategy may offer additional advantages over a non-collaborative strategy. The challenge lies in combining the information received from users organized in a collaborative manner. The purpose of the present article is to propose a collaborative spectrum allocation model for a decentralized cognitive radio network. In this sense, the cognitive radio user shares his information with other neighboring network users. The shared information is characterized through five levels of collaboration (10%, 20%, 50%, 80% and 100%) where each one represents the percentage of information that is to be shared for training and subsequent model validation. The comparative assessment is carried out with the decision-making multi-criteria algorithms SAW and TOPSIS. The results reveal that the SAW algorithm outperforms the alternatives under different scenarios and collaboration levels in terms of the handoff metric.
