https://doi.org/10.1007/978-3-642-93383-7results in more demand of the radio spectrum. Due to the scarcity of radio spectrum and the under-utilization of assigned spectrum, government regulatory bodies have started to review their spectrum allocation policies so as to implement opportunistic spectrum access (sharing) through cognitive femt

Hirofumi Uchida,Arito Ono,Iichiro Uesugi without any reasonable doubt detect the presence or the absence of the primary user (PU). Therefore, spectrum sensing is core to the performance of cognitive radio networks and it is shown in this paper that deploying multiple input multiple output (MIMO) at the SU, improves the performance.

The Big Meaning of Small Messagesa little is addressing rural environments at 2.4 GHz. In this work, we consider empirical path loss models in wireless networks at 2.4 GHz, using off-the-shelf 802.11n. We define three scenario usually observed in rural environment: free space, raised space and built space. Afterwards, we do a measu
