This paper studies a distributed resource allocation problem for a multiagent network with a
time-varying digraph. Each agent in the network is associated with a local variable …

Underwater environments have never been much of a constraint to the rich animal life they
support at all depths of our seas and oceans. Indeed, nature has taken advantage of this …

We introduce a new structure for a set of points in the plane and an angle α α, which is
similar in flavor to a bounded-degree MST. We name this structure α α-MST. Let P be a set of …

Digital media manipulation has become easily performed at personal level with the rapidly
growth of Technology. Presenting an issue of protecting digital media integrity …

Let P be a set of points in the plane, representing transceivers equipped with a directional
antenna of angle α and range r. The coverage area of the antenna at point p is a circular …

For any angle α< 2 π, we show that any connected communication graph that is induced by
a set P of n transceivers using omni-directional antennas of radius 1, can be replaced by a …

We consider the following Antenna Orientation Problem: Given a connected Unit Disk Graph
(UDG) formed by n identical omnidirectional sensors, what is the optimal range (or radius) …

We study the problem of connectivity in wireless networks in which each node uses a single
directional antenna. We consider the symmetric model of communication with directional …

The coverage area of a directional antenna located at point p is a circular sector of angle α,
whose orientation and radius can be adjusted. The interference at p, denoted I (p), is the …

We study the Voronoi Diagram of Rotating Rays, a Voronoi structure where the input sites
are rays and the distance function between a point and a site/ray, is the counterclockwise …
