Coverage area management for wireless sensor networks
International Journal of Network Management, 2006AbstractIn this work, we present a self‐management service for Wireless Sensor Networks (WSNs) that automatically controls the network redundancy. Based on a density control function, this service improves the monitoring potential of the sensor nodes. Our simulation experiments show that this self‐management service provides good and lasting coverage ...

Homogeneous Hierarchical Composition of Areas in Multi-robot Area Coverage
2007Multi-robot area coverage poses several research challenges. The challenge of coordinating multiple robots' actions coupled with the challenge of minimizing the overlap in coverage across robots becomes even more complex and critical when large teams and large areas are involved.

On the coverage area in broadcast ad hoc networks
2012 3rd IEEE International Conference on Network Infrastructure and Digital Content, 2012In this paper, we first define the problem of computation of the potential hidden node area and the extra coverage area that can benefit from rebroadcasts in broadcast ad hoc networks and abstract two types of computations as a geometric coverage area computation problem. Then, under two distinct distributions of the nodes in the network, we derive the

Coverage Area Performance for Multiple Interfering UAVs
2019 IEEE Global Communications Conference (GLOBECOM), 2019Unmanned aerial vehicles (UAVs) have the capability of supplementing as well as improvising terrestrial cellular communications as aerial base stations to improve network coverage. This puts significance on the effective deployment of multiple UAVs while maximizing the coverage area in presence of co- channel interference generated by these UAVs.

On area coverage reliability of wireless sensor networks
2011 IEEE 36th Conference on Local Computer Networks, 2011In this paper we consider wireless sensor networks (WSNs) whose nodes can fail independently of each other during normal operation. For successful operation, a network is required to provide sensing coverage of an aggregate area that exceeds a given application-specific coverage requirement.

The Area Coverage Algorithm to Maintain Connectivity for WSN
2009 Ninth IEEE International Conference on Computer and Information Technology, 2009The Coverage Control Technology is the 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 user sense demands and network connection. Among this technology, localized area coverage algorithm in the study of area coverage technology is gradually attracting ...

On area coverage problems in directional sensor networks
The International Conference on Information Networking 2011 (ICOIN2011), 2011A directional sensor network is composed of many directional sensor nodes. Unlike conventional omni-directional sensors that always have an omni-angle of sensing range, directional sensors may have a limited angle of sensing range due to technical constraints or cost considerations.

Multi-robot area coverage with limited visibility
International Joint Conference on Autonomous Agents and Multiagent Systems, 2010We address the problem of multi-robot area coverage and present a new approach in the case where the map of the area and its static obstacles are known and the robots have a limited visibility range. The proposed method starts by locating a set of static guards on the map of the target area and then builds a graph called Reduced-CDT, a new environment ...

Accurate playfield detection using Area-of-Coverage
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010Playfield detection is an important task in sports video content analysis, as it provides the ground for further operations such as object detection, object tracking or semantic event highlight and summarization. Traditional approaches of playfield detection usually rely on the homogeneity cue of the field pixels' color to separate it from other areas ...
