Wireless Sensor Networks (WSNs) are large-scale and high-density networks that typically
have coverage area overlap. In addition, a random deployment of sensor nodes cannot fully …

The limited energy supply of wireless sensor networks poses a great challenge for the
deployment of wireless sensor nodes. In this paper, we focus on energy-efficient coverage …

Wireless sensor networks (WSNs) have drawn much research attention in recent years due
to the superior performance in multiple applications, such as military and industrial …

Coverage is one of the important performance indexes in wireless sensor networks. When
the target is covered by k degrees by the sensor, more redundant data are generated, which …

One of the wireless sensor networks applications is to sense a discrete set of targets lying on
the field and maintain connectivity with the sink for data transmission. In addition, it needs to …

A wireless sensor network (WSN) is composed of a group of small power-constrained nodes
with functions of sensing and communication, which can be scattered over a vast region for …

Due to the constrained energy and computational resources available to sensor nodes, the
number of nodes deployed to cover the whole monitored area completely is often higher …

Coverage is a primary metric for ensuring the quality of services provided by a wireless
sensor network (WSN). In this paper, we focus on the k-coverage problem, which requires a …

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 …

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