Abstract In a Wireless Sensor Network (WSN), when a large amount of sensors are
randomly deployed into a detection area, an efficient sleep/active scheduling for sensors to …

For various applications, sensors are deployed to monitor belt regions to guarantee that
every movement crossing a barrier of sensors will be detected in real-time with high …

Modern, inherently dynamic systems are usually characterized by a network structure which
is subject to discrete changes over time. Given a static underlying graph, a temporal graph …

Coverage of wireless sensor networks is a fundamental problem which has been studied for
more than two decades. In duty cycle based wireless sensor networks, the nodes are …

The motivation for writing this book came from our previous research works on sensor
coverage. They received a large number of citations and this number grows rapidly each …

Barriers are utilized for various tasks in security, environmental monitoring, penetration
detection and reconnaissance. It is highly necessary to consider how to support pedestrian …

Information barrier coverage has been widely adopted to prevent unauthorized invasion of
important areas in Internet of Things. As sensors are typically placed outdoors, they are …

Border surveillance for intrusion detection is an important application of wireless sensor
networks. Given a set of mobile sensors and their initial positions, how to move these …

Witnessing broad energy‐critical applications of barrier coverage in mobile and wireless
sensor networks, emerging practical applications have recently brought a new barrier …

Critical homeland security applications, such as international border surveillance and zone
monitoring in case of biological attacks, require the timely creation of a barrier of sensors …
