In this paper we deal with an extension of the crossing postman problem to design routes
that have to visit different shapes of dimensional elements rather than edges. This problem …

There is a strong demand for covering a large area autonomously by multiple UAVs
(Unmanned Aerial Vehicles) supported by a ground vehicle. Limited by UAVs' battery life …

Sensing data gathering is an important and fundamental issue in the Internet of Things.
However, for battery-powered sensors, energy depletion is unavoidable. Using mobile sinks …

This paper presents a wireless data collection frame-work that employs an unmanned aerial
vehicle (UAV) to efficiently gather data from distributed IoT sensors deployed in a large area …

This paper deals with two different route design problems in a continuous space with
neighbours and barriers: the shortest path and the travelling salesman problems with …

This paper deals with facility location problems in a continuous space with neighbours and
barriers. Each one of these two elements, neighbours and barriers, makes the problems …

Abstract The Travelling Salesman Problem with Neighborhoods (TSPN), as an extension of
the broadly studied Travelling Salesman Problem, has many practical applications in …

For a given polygonal region P, the Lawn Mowing Problem (LMP) asks for a shortest tour T
that gets within Euclidean distance 1 of every point in P; this is equivalent to computing a …
