Wireless sensor networks constitute the platform of a broad range of applications related to
national security, surveillance, military, health care, and environmental monitoring. The …

In this paper, we study deployment patterns to achieve full coverage and k-connectivity (k≤
6) under different ratios of the sensor communication range (denoted by R c) to the sensing …

Barrier coverage is a critical issue in wireless sensor networks for various battlefield and
homeland security applications. The goal is to effectively detect intruders that attempt to …

To make a network last beyond the lifetime of an individual sensor node, redundant nodes
must be deployed. What sleep-wake-up schedule can then be used for individual nodes so …

Intrusion detection is an important problem in sensor networks. Prior works in static sensor
environments show that constructing sensor barriers with random sensor deployment can be …

Mission-driven sensor networks usually have special lifetime requirements. However, the
density of the sensors may not be large enough to satisfy the coverage requirement while …

A set of sensors establishes barrier coverage of a given line segment if every point of the
segment is within the sensing range of a sensor. Given a line segment I, n mobile sensors in …

Deploying wireless sensor networks to provide guaranteed barrier coverage is critical for
many sensor networks applications such as intrusion detection and border surveillance. To …

For some sensor network applications, the problem of sweep coverage, which periodically
covers POIs (Points of Interest) to sense events, is of importance. How to schedule minimum …

The paper proposed a distributed algorithm, namely CoBRA (Cone-based Barrier coveRage
Algorithm), to achieve barrier coverage in wireless camera sensor networks (WCSNs). To …
