Mobile data traffic has been growing exponentially over the past few years. A report from Cisco shows that the mobile data traffic in 2014 grew 69 percent and was nearly 30 times the size of the entire global Internet in 2000 [item 1) in the Appendix

In this work, we analyze a distributed cooperative spectrum sensing scheme where N secondary users (SUs) of a cognitive wireless net-work make a joint decision on the primary user (PU) presence based on an agreement reached through interchanging of S

In this paper, we analyze cooperative wireless networks (primary networks) operating under randomly located interfering nodes (secondary networks). Applying Poisson point processes to modeling of network and interfering node locations, we derive stat

In this letter, we analyze the capacity of a class of generalized fading channels represented by two-wave with diffuse power (TWDP) fading models. We obtain a new representation of TWDP fading model as a mixture of gamma distributions and apply the n

In this paper, we present expressions for the cumulative distribution function (CDF) of a specially constructed random variable (RV) represented by the ratio of two generalized RVs. The obtained theoretical results are used to evaluate the outage pro
