In Wireless Sensor Networks (WSNs), coverage is a critical issue that has a major bearing
on the quality of sensing over the target region. In this paper, we study the coverage of a …

We consider the k-barrier coverage problem, that is, the problem of deploying sensors on a
border or perimeter to ensure that any intruder would be detected by at least k sensors. With …

In some mobile wireless sensor network applications, it is not necessary to monitor the entire
field all the time, and only a number of critical points or points of interest (POIs) need to be …

Barrier coverage is an important issue in wireless sensor networks. In this paper, we study
the problem of how to find barrier gaps in weak barrier coverage and mend gaps via sensor …

Energy harvesting is emerging as a promising technology to extend the lifetime of wireless
sensor networks, which is referred to as rechargeable sensor networks (RSNs), This paper …

Applying wireless sensor network to emergency management is helpful to predict latent
disaster and prevent or lessen the harm. In some cases of emergency management, it is not …
