Active Area Coverage from Equilibrium [PDF]
EasyChair Preprints, 2019 This paper develops a method for robots to integrate stability into actively seeking out informative measurements through coverage. We derive a controller using hybrid systems theory that allows us to consider safe equilibrium policies during active data collection.

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 ...

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.

Area coverage under low sensor density [PDF]
2014 Eleventh Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2014 This paper presents a solution to the problem of monitoring a region of interest (RoI) using a set of nodes that is not sufficient to achieve the required degree of monitoring coverage. In particular, sensing coverage of wireless sensor networks (WSNs) is a crucial issue in projects due to failure of sensors.

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.

Local Coverage Optimization Strategy Based on Voronoi for Directional Sensor Networks
Sensors, 2016 In this paper, we study the area coverage of directional sensor networks (DSNs) with random node distribution. The coverage of DSNs depends on the sensor’s locations, the sensing radiuses, and the working directions, as well as the angle of view (AoV ...
