According to the World Health Organization, most of the world population is affected by chronic diseases, obesity, cardiovascular diseases and diabetes while another dominant problem is of aging population. Thus, it is desirable to have cost effective solutions for health monitoring, especially for countries that have minimum conventionally trained healthcare staff and infrastructure. Healthcare has shifted from hospital dominant services to patient dominant services which has thrived WBANs to p...

Recently, RSS fingerprint-based location has been considered as a low-complexity solution for indoor localization. However, constructing a fingerprint map requires a great amount of manual effort to achieve a high location accuracy. In this paper, we present a refinement method to reduce the necessary manual effort without degrading the location accuracy. This method transforms a coarse-gained fingerprint map containing only a small number of offline samples into a high-density fingerprint map b...

Massive multiple-input multiple-output (MIMO) systems, in which base stations are equipped with a large number of antennas in a two-dimensional antenna array, is one of the most promising technologies to improve the spectral efficiency of the fifth generation mobile communication systems (5G). Since there is no short-term channel reciprocity, the frequency-division duplexing (FDD) massive MIMO system has to obtain channel state information with the help of uplink feedback with acceptable overhea...

Broadcasting is an important phenomenon, because it serves as simplest mode of communication in a network, via which each node disseminates information to their neighboring nodes simultaneously. Broadcasting is widely used in various kind of networks, such as wireless sensor networks, wireless networks, and ad-hoc networks. Similarly, in cognitive radio networks (CRNs), broadcasting is also used to perform many tasks including neighbor discovery, spectrum mobility, spectrum sharing, and dissemin...

This paper analyzes the performance of quadrature spatial modulation (QSM) multiple-input multiple-output (MIMO) system in cooperative decode and forward (DF) networks over correlated and imperfect \(\eta \)–\(\mu \) fading channels. QSM is a recently proposed propitious MIMO technique that promises significant advantages over conventional MIMO schemes including high spectral efficiency with single RF-chain transmitter and very low receiver complexity. In this study, DF cooperative communication...

The legacy long term evolution (LTE) networks suffer from scalability problems when a massive number of Internet of Things devices enter the network simultaneously. In this paper, we investigate the root causes of the overload problems due to a massive number of machine devices when accessing to the LTE network, and evaluate current standardized solutions of 3GPP in terms of overload aspects. As a result, we derive the limitations of 3GPP standardized solutions, and then suggest a novel group-ba...

Rendezvous is a fundamental challenge in cognitive radio networks where users can find each other on a specific channel and hence establish a communication link. Most previous works are based on the strong assumption that users are able to find a set of available channels after the spectrum sensing stage and the status of these channels are stable all the time, which, however, may be unrealistic in some scenarios. As a solution, we design a fair channel hopping protocol with dynamic channel stat...

This paper explores an end-to-end outage probability experienced in a bidirectional relay assisted communication where the relay is assumed to be equipped with an RF energy harvesting circuit. First, the closed-form expression for the outage of the system is derived. This is followed by the formulation of an unconstrained optimization problem to achieve minimum outage probability with respect to the relay placement and consequent time allocation for energy harvesting. The system model is further...
