Abstract Heterogeneous Wireless sensor networks (WSNs) deploy hundreds to thousands of
low-cost sensors in their area detection, and these heterogeneous nodes present the main …

We investigate the physical-layer security of an uplink wireless time-division multiple-access
channel with energy-harvesting source nodes. We consider a set of source nodes equipped …

The deployment of a wireless network greatly affects the system capacity, which is difficult to
be optimized with massive devices and complicated propagation environment. The machine …

The traffic in the wireless networks has become diverse and fluctuating both spatially and
temporally due to the emergence of new wireless applications. The purpose of this paper is …

In this work, we have studied connectivity probability, efficiency, load balancing technique,
and delay of the heterogeneous networks. In the 5G Software-Defined Heterogeneous …

The wireless cellular networks have been witnessing a rapid growth in video-on-demand
(VoD) streaming traffic. Different from conventional voice and data applications, VoD …

In order to make full use of the ultra-dense architecture and effectively serve the space and
time fluctuation, the transmission mechanism should be redesigned under the constraints of …

A plethora of application scenarios are rapidly emerging within the context of the Internet of
Things (IoT) in possibly every industrial and market vertical. Accordingly, the wireless …

We consider a wireless ad hoc network in the presence of eavesdroppers (EDs), where the
nodes are distributed according to independent Poisson point processes (PPPs). The …
