In last two decades, various monitoring systems have been designed and deployed in urban
environments, toward the realization of the so called smart cities. Such systems are based …

With the proliferation of wireless devices, wireless networks in various forms have become
global information infrastructure and an important part of our daily life, which, at the same …

Robotic mining equipment plays an increasingly important role in the coal mining industry.
Due to the complexity of the confined underground environment, available localization …

We study a heterogeneous two-tier wireless sensor network in which N heterogeneous
access points (APs) collect sensing data from densely distributed sensors and then forward …

The application of tiny body sensors to collect, process, store, analyze, and retrieve medical
information from a human body is a part of the Internet of Medical Things (IoMT). IoMT helps …

Optimal deployment and movement of multiple unmanned aerial vehicles (UAVs) are
studied. The considered scenario consists of several ground terminals (GTs) communicating …

We study the heterogeneous wireless sensor networks (WSNs) and propose the necessary
condition of the optimal sensor deployment. Similar to that in homogeneous WSNs, the …

We study a mobile wireless sensor network (MWSN) consisting of multiple mobile sensors or
robots. Three key factors in MWSNs, such as sensing quality, energy consumption, and …

One of the major applications of wireless sensor networks (WSNs) is the navigation service
for emergency evacuation, the goal of which is to assist people in escaping from a …

In order to compute the marginal probability density function (PDF) with Gaussian belief
propagation (BP), it is important to know whether it will converge in advance. By describing …
