In this paper, we investigate the network connectivity of wireless sensor networks with
directional antennas. In particular, we establish a general framework to analyze the network …

Rendezvous control of multiple robots without losing network connectivity has important
implications in multi-robot system including formation control, coordinated task assignments …

At present, cellular coverage in many rural areas remains intermittent. Mobile operators may
not be willing to deploy expensive network infrastructure to support low-demand regions. For …

We propose a novel mobile robot teleoperation interface that demonstrates the applicability
of robot-aided remote telepresence system with a virtual reality (VR) device in a virtual tour …

Directional antenna-based aerial networking (DAAN) is referred as a promising technology
to meet the dynamic data demands for unmanned aerial vehicles (UAVs). However, the …

Mobile robots rely on wireless networks for sharing sensor data from remote missions. The
robot's spatial network quality will vary considerably across a given mission environment …

In this paper, we present a directional antenna-based leader–follower robotic relay system
capable of building end-to-end communication in complicated and dynamically changing …

In recent years, with the steady and rapid growth of the national economy, various industries
have developed rapidly and the resulting fire accidents have also been on the rise. This …

Water pollution has caused increased incidence of algal growth around the globe. Harmful
algae blooms result in massive economic losses. In this paper, a multi-robot based task …

In multi-robot applications, consensus control and coordination are vital and potentially
repetitive tasks. To circumvent practical limitations such as a global localization system …
