Cognitive radio is an essential technology to overcome fixed spectrum allocation problems and improve its use through dynamic spectrum access techniques. Spectral decision-making is a function of the cognitive cycle that aims to choose the best spectral alternative among a set of finite possibilities. An inadequate process of decision-making can significantly affect the network parameters. Therefore, it is important to determine the best strategy and if this decision making should be collaborative. The present research analyzes the performance of failed handoff rate according to the amount of information shared between secondary users. The aforementioned information corresponds to the spectral occupancy for the GSM frequency band, that is characterized by a set of users and five levels of collaboration, 10%, 20%, 50%, 80% and 100%, where each level represents the percentage of users are part of the training model implemented. The decision-making process is carried out by using two multi-criteria techniques: Feedback Fuzzy Analytical Hierarchical Process (FFAHP) and Simple Additive Weighting (SAW). Based on the obtained percentage ratios and the information shared, it is determined that for the given number of failed handoffs, the level of collaboration that leads to efficient results is between 20% and 50%.
