$k$ -Coverage Estimation Problem in Heterogeneous Camera Sensor Networks With Boundary Deployment

Desperate Coverage Problem in Mission-Driven Camera Sensor Networks

Recently, camera sensor network is attracting huge amount of attention due to the growing popularity of multimedia applications. This paper investigates a new scheduling problem in camera sensor network whose goal is to cover a set of targets as efficiently as possible during a given mission period. In particular, we consider a desperate situation in which we may not have enough camera sensors ...

Barrier Coverage in Mobile Camera Sensor Networks with Grid-Based Deployment

Barrier coverage is a critical issue in wireless sensor networks for many practical applications, e.g., national border monitoring, security surveillance and intruder detection, etc. Its aim is to detect intruders that attempt to cross the protected region. Available works mainly focused on the barrier coverage of directional sensors (e.g., cameras), which have limited coverage area and sensing...

Coverage Quality in Visual Sensor Networks

Algorithms for the m-Coverage Problem and k-Connected m-Coverage Problem in Wireless Sensor Networks

Abstract. An important issue in deploying a wireless sensor network (WSN) is to provide target coverage with high energy efficiency and faulttolerance. In this paper, we study the problem of constructing energy-efficient and fault-tolerant target coverage with the minimal number of active nodes which form an m-coverage for targets and a k-connected communication subgraph. We propose two heurist...

Node Deployment with k-Connectivity in Sensor Networks for Crop Information Full Coverage Monitoring

Wireless sensor networks (WSNs) are suitable for the continuous monitoring of crop information in large-scale farmland. The information obtained is great for regulation of crop growth and achieving high yields in precision agriculture (PA). In order to realize full coverage and k-connectivity WSN deployment for monitoring crop growth information of farmland on a large scale and to ensure the ac...
