Online Drone Coverage of Targets on a Line
Stefan Dobrev, Konstantinos Georgiou, Evangelos Kranakis +5
We study a problem of online targets coverage by a drone or a sensor that is equipped with a camera or an antenna of fixed half-angle of view . The targets to be monitored appea…
The En Route Truck-Drone Delivery Problem
Danny Krizanc, Lata Narayanan, Jaroslav Opatrny +1
We study the truck-drone cooperative delivery problem in a setting where a single truck carrying a drone travels at constant speed on a straight-line trajectory/street. Delivery to…
Group Evacuation on a Line by Agents with Different Communication Abilities
Jurek Czyzowicz, Ryan Killick, Evangelos Kranakis +5
We consider evacuation of a group of autonomous mobile agents (or robots) from an unknown exit on an infinite line. The agents are initially placed at the origin of the…
The Bike Sharing Problem
Jurek Czyzowicz, Konstantinos Georgiou, Ryan Killick +5
Assume that autonomous mobile agents and single-agent transportation devices (called {\em bikes}) are initially placed at the left endpoint of the…
Time-Energy Tradeoffs for Evacuation by Two Robots in the Wireless Model
Jurek Czyzowicz, Konstantinos Georgiou, Ryan Killick +6
Two robots stand at the origin of the infinite line and are tasked with searching collaboratively for an exit at an unknown location on the line. They can travel at maximum speed $…
Linear Search with Terrain-Dependent Speeds
Jurek Czyzowicz, Evangelos Kranakis, Danny Krizanc +3
We revisit the linear search problem where a robot, initially placed at the origin on an infinite line, tries to locate a stationary target placed at an unknown position on the lin…
Search on a Line by Byzantine Robots
Jurek Czyzowicz, Konstantinos Georgiou, Evangelos Kranakis +4
We consider the problem of fault-tolerant parallel search on an infinite line by robots. Starting from the origin, the robots are required to find a target at an unknown locati…
Evacuating Robots from a Disk Using Face-to-Face Communication
Jurek Czyzowicz, Konstantinos Georgiou, Evangelos Kranakis +3
Assume that two robots are located at the centre of a unit disk. Their goal is to evacuate from the disk through an exit at an unknown location on the boundary of the disk. At any…
Optimal online and offline algorithms for robot-assisted restoration of barrier coverage
J. Czyzowicz, E. Kranakis, D. Krizanc +2
Cooperation between mobile robots and wireless sensor networks is a line of research that is currently attracting a lot of attention. In this context, we study the following proble…
