Abstract

In addition to traditional performance metrics in the context of spectrum sensing in cognitive radio networks, energy consumption has received a lot of attention, as it is a limited resource. In this article, the performance of spectrum sensing based on the energy detector and also the energy consumption of the network is analyzed in three cooperative sensing modes: data fusion, decision fusion and hybrid fusion. The presented computer simulation results make use of a realistic model in terms of the location and mobility of the terminals, and of the cluster formation rule in the hybrid fusion mode.
