It is essential to estimate the position of primary users (PUs) for the further development of
cognitive radio (CR) networks. Great efforts have been done to seek for localization …

In this paper, we propose a novel resource allocation scheme for co-channel interference
avoidance in LTE heterogeneous networks with universal spectrum reuse where both macro …

With the integration of smartphone into daily life, end users store a large amount of sensitive
information into Android device. For protecting the sensitive information, a method of multi …

This paper proposes a reserved channel based spectrum handover mechanism for cognitive
heterogeneous networks (HetNet). To properly handover secondary users from Macro to …

The energy expenditure of cellular networks is increasing rapidly due to high demand of
data services by the subscribers. This subsequently gives rise to the CO2 emission which is …

There is a class of projects that can only be accomplished via agile practices due to their
complexity and risks. It is rare for such a project to be staffed with newbies but it happened …

We consider a heterogeneous Long Term Evolution Advanced (LTE-A) network where a
cognitive femtocell operates in the coverage area of a traditional macrocell sharing the same …

The long-term evolution and advancement (LTE-A) of the 5G wireless network depends
critically on energy consumption. Many existing solutions focus on limiting power constraints …

Channel allocation possibilities of femtocells are analyzed in this work. Femtocells have
gained importance in the recent times because of their scope to offer better frequency reuse …

Recently, cognitive radio (CR) technology is proposed to be combined with femtocell
networks, which enables femtocells to access the available spectrum bands in an …
