Several wireless services make use of the spectrum for communication, from space radio communication to a simple wireless computer network. However, the considerable amount of services that make use of spectrum in the last years, has been responsible for its limited availability and inefficiency.. Cognitive networks or cognitive radio networks, are a technology that offer the efficient use of spectrum through opportunistic access to frequency bands. Throughout the cognitive radios scenario, this work will present a variation of the JENNA neighbors discovery algorithm. In addition to that, this research will propose a sensing model for a more efficient approach.
