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 …

We consider several variations of the problems of covering a set of barriers (modeled as line
segments) using sensors that can detect any intruder crossing any of the barriers. Sensors …

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 …

In this paper, we study the problem of moving nn sensors on a line to form a barrier
coverage of a specified segment of the line such that the maximum moving distance of the …

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

One of the most fundamental tasks of wireless sensor networks is to provide coverage of the
deployment region. We study the coverage of a line interval with a set of wireless sensors …

We study the problem of achieving maximum barrier coverage by sensors on a barrier
modeled by a line segment, by moving the minimum possible number of sensors, initially …

Emerging IoT applications have brought up new coverage problems with sink-based mobile
sensors. In this paper, we first focus on the MinSum Sink-based Line Barrier Coverage …

Assume that n sensors with identical range r= f (n)⁄ 2 n, for some f (n)≥ 1 for all n, are thrown
randomly and independently with the uniform distribution in the unit interval [0, 1]. They are …

We study the barrier coverage problem using relocatable sensor nodes. We assume each
sensor can sense an intruder or event inside its sensing range. Sensors are initially located …
