Coverage area maximization with parallel simulated annealing

Expert Systems with Applications, 2022
This study provides a system that determines where to locate 𝑘 disks-like services of radius 𝑟 so that they globally cover as much as possible a region of demand. It is an NP-hard problem with notorious applications in the facility location field when locating multiple warning sirens, cellular towers, radio stations, or pollution sensors covering as ...

On Multi-robot Area Coverage [PDF]

International Joint Conference on Autonomous Agents and Multiagent Systems, 2010
Area coverage is one of the emerging problems in multi-robot coordination. In this task a team of robots is cooperatively trying to observe or sweep an entire area, possibly containing obstacles, with their sensors or actuators. The goal is to build an efficient path for each robot which jointly ensure that every single point in the environment can be ...

A Two-Phase Coverage-Enhancing Algorithm for Hybrid Wireless Sensor Networks

Sensors, 2017
Providing field coverage is a key task in many sensor network applications. In certain scenarios, the sensor field may have coverage holes due to random initial deployment of sensors; thus, the desired level of coverage cannot be achieved.

The Maximum Coverage Set Calculated Algorithm for WSN Area Coverage

Journal of Networks, 2010
The Coverage Control Technology is one of the basic technologies of wireless sensor network, and is mainly concerned about how to prolong the network lifetime on the basis of meeting users’ perception demand. Among this, in the study of area coverage, the set K-cover algorithm is broadly accepted because that it can prolong network lifetime rather well.

Global Optimization of UAV Area Coverage Path Planning Based on Good Point Set and Genetic Algorithm

Aerospace, 2022
When performing area coverage tasks in some special scenarios, fixed-wing aircraft conventionally adopt the scan-type of path planning, where the distance between two adjacent tracks is usually less than the minimum turning radius of the aircraft.
