This paper shows the problems that exist in the routing of cognitive radio networks taking into acmaximicount a very important parameter as the behavior of throughput. In this way, a scenario for a WirelessAd Hoc Network with features of cognitive ra

The Wireless Sensor Network (WSN) consists of a large number of tiny devices called nodes, and these nodes are generally limited in power and they are randomly deployed in a geographical area for monitoring purpose. Because of the large number of nod

The main objective of the thesis is to devise a reliable non-cooperative spectrum sensing system that is able to detect noiselike signals. We harness the strength of cepstral analysis to develop a system able to detect spread spectrum signals. We hav

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

The scarcity of radio spectrum is one of the most urgent issues at the forefront of future network research that is yet to be addressed. To address the problem of spectrum usage efficiency, the cognitive radio (CR) concept was proposed. The challenge

Different priorities of users’ access are defined in cognitive radio networks (CRNs) in order to differentiate the spectrum usage: primary user (PU) preferentially occupies the band, whereas secondary users (SUs) can only have access to the band if
