    Distributed algorithms for barrier coverage using relocatable sensors

    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 at arbitrary positions on the ...

    Distributed Barrier Coverage with Relocatable Sensors

    A wireless sensor can detect the presence of an intruder in its sensing range, and is said to cover the portion of a given barrier that intersects with its sensing range. Barrier coverage is achieved by a set ...

    Complexity of Barrier Coverage with Relocatable Sensors in the Plane

    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 are initially located in...
