This paper focuses on spectrum handoffs in a
cognitive radio network where secondary (unlisenced) users (i.e.
cognitive radios) opportunistically use frequency channels as
long as the aggregate interference caused at the primary
(licensed) users does not exceed a certain threshold. When
harmful interference is caused to a primary user, or when the
quality of service perceived by a secondary user is not
satisfactory, the secondary user has to initiate a spectrum
handoff to quickly vacate the channel it is occupying. The
proposal in this paper is a fuzzy-based approach able to make
effective spectrum handoff decisions in a context characterized
by uncertain, incomplete and heterogeneous information.
