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 ...

K-coverage in regular deterministic sensor deployments [PDF]
, 2013 An area is k-covered if every point of the area is covered by at least k sensors. K-coverage is necessary for many applications, such as intrusion detection, data gathering, and object tracking.

Multi-robot repeated area coverage [PDF]
Autonomous Robots, 2013 We address the problem of repeated coverage of a target area, of any polygonal shape, by a team of robots having a limited visual range. Three distributed Cluster-based algorithms, and a method called Cyclic Coverage are introduced for the problem. The goal is to evaluate the performance of the repeated coverage algorithms under the effects of the ...

A Design Approach for Simultaneous Cooperative Interception Based on Area Coverage Optimization
Drones, 2022 In this paper, a design approach for simultaneous cooperative interception is presented for a scenario where the successful handover cannot be guaranteed by a single interceptor due to the target maneuver and movement information errors at the handover ...

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.
