Deploying wireless sensor networks (WSNs) to form a barrier that provides surveillance
against illegal intruders (or targets) is a fundamental sensor-allocation problem. In this …

Most existing works on barrier coverage assume that sensors are deployed in a two-
dimensional (2D) long thin belt region, where a barrier is a chain of sensors from one end of …

Recently, full-view coverage has been introduced to capture intruders from multiple
directions in the camera sensor networks. It is more efficient than traditional coverage in …

Unmanned Aerial Vehicles (UAVs) is an emerging technology with many applications in
surveillance, remote sensing, transportation, scientific research, search and rescue, and …

Sensor barrier coverage has been recognized as an appropriate coverage model for
intrusion detection, and many achievements have been obtained in two-dimensional …

A set of wireless sensors is called a barrier cover if they can monitor the boundary of an area
so that an intruder cannot enter the area without being found by any sensor. The quality of a …

Nowadays the most important key point in the design of wireless sensor networks (WSNs) is
the sensor coverage point and network connectivity. The main practical issue in designing …

Barrier coverage is one of the research hot spots of wireless sensor network coverage
control. In order to fix the defects and deficiencies of the network, which is composed of all …

Barrier coverage in two-dimensional (2D) terrestrial wireless sensor networks is an
important problem, and many achievements have been obtained in recent years. However …

Sensor networks are formed by fixed or mobile sensor nodes and their functions are to
capture the events that occur within a certain area and then relay to a central node …
