The problem of having sufficient coverage is an essential issue in wireless sensor network
(WSN). A high coverage rate delivers a higher quality of service. The aim of coverage …

The paper describes the concept of coverage problem in the wireless sensor networks
(WSNs). The issue of quality of service is more closely related to the coverage problem in …

Wireless sensor networks constitute the platform of a broad range of applications related to
national security, surveillance, military, health care, and environmental monitoring. The …

A virtual square grid-based coverage algorithm (VSGCA) is proposed in this paper. Each
sensor node divides its sensing range into virtual square grids, if all the grids are covered by …

Coverage problem is an important issue in wireless sensor networks, which has a great
impact on the performance of wireless sensor networks. Given a sensor network, the …

Most existing research considers homogeneous sensor networks, which suffer from
performance bottleneck and poor scalability. In this paper, we adopt a heterogeneous …

Abstract A Wireless Sensor Network (WSN) is used to monitor an area for events. Each node
in the WSN has a sensing range and a communication range. The sensing coverage of a …

This paper describes a basic coverage issue, and proposes a scheme named Grid Scan
which is applied to calculate the basic coverage rate with arbitrary sensing radius of each …

Wireless sensor networks have a broad range of applications in the military, surveillance,
environment monitoring, and healthcare fields. Coverage of sensor networks describes how …

We pinpoint a new sensor self-deployment problem, constructing focused coverage around
a point of interest (POI), and introduce an evaluation metric, coverage radius. We propose …
