A survey on area coverage in wireless sensor networks
2014 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2014In recent years, Wireless Sensor Networks (WSNs) have gained much attention because of its varying applications from catastrophic region to industrial and household region. In few applications, sensors are deployed in extreme environmental conditions. Hence, node access is not possible in that scenario.

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 ...

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 ...

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.

A Preliminary Work of Distributed Area Coverage in WSNs
2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019Coverage is one of the most important issues in wireless sensor networks. With the development of charging technology, more and more wireless sensors are equipped with solar cells. Many studies have proposed centralized solutions for coverage problem.

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.

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 ...

Distributed area coverage using robot flocks
2009 World Congress on Nature & Biologically Inspired Computing (NaBIC), 2009We consider the problem of distributed, autonomous area coverage using a team of mobile mini-robots that have limited sensing and computation capabilities. Specifically, we investigate the following hypothesis - can mini-robots organized in small teams improve the efficiency of area coverage as compared to area coverage using robots that are not ...

A rapid scan area-coverage communication satellite
7th Communications Satellite Systems Conference, 1978A satellite concept with a high-gain, movable spot-beam is examined. Communication with individual earth stations is achieved by time sharing a single channel in the time-division multiple access (TDMA) mode. A TDMA burst organization is proposed, and estimates of burst lengths, beam switching intervals, and buffer storage size are made for a network ...
