Coverage of interest points and network connectivity are two main challenging and
practically important issues of Wireless Sensor Networks (WSNs). Although many studies …

As the binary sensing model is a coarse approximation of reality, the probabilistic sensing
model has been proposed as a more realistic model for characterizing the sensing region. A …

Wireless sensor networks (WSNs) provide a convenient way to monitor the physical
environment. They consist of a large number of sensors that have sensing, computing, and …

This paper studies deterministic sensor deployment for barrier coverage in wireless sensor
networks. Most of existing works focused on line-based deployment, ignoring a wide …

Network lifetime maximization with guaranteed coverage is an important issue in wireless
sensor networks. Based on our recently proposed confident information coverage (CIC) …

Barrier coverage is a critical issue in wireless sensor networks for security applications (eg,
border protection), the performance of which is highly related with locations of sensor nodes …

The barrier coverage of a wireless sensor network is an important surveillance application of
Internet of Things. Barrier coverage guarantees that all intruders traversing the protected …

Intruder detection is an important application in Wireless Sensor Networks (WSNs). Barrier
coverage, which requires much fewer sensors than full coverage, is broadly known as an …

Recently, the barrier-coverage of wireless sensor network received huge attention thanks to
the important applications such as border protection. In practice, sensor nodes are subject to …

Intruder detection is an important application in wireless sensor networks. This paper
focuses on detecting smart intruders whose purpose is to cross the monitored area and who …
