Given a set of points in the plane, we want to establish a connected spanning graph
between these points, called connection network, that consists of several disjoint layers …

Sensors typically use wireless transmitters to com-municate with each other. However,
sensors may be located in a way that they cannot even form a connected network (eg, due to …

Motivated by applications to wireless sensor networks, we study the following problem. We
are given a set S of wireless sensor nodes, given as a multiset of points in a normed space …

We investigate the problem of converting sets of sensors into strongly connected networks of
sensors using multiple directional antennae. Consider a set S of n points in the plane …

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 …

Consider a network of n directional antennae in the plane. We consider the problem of
efficient neighbor discovery in a (synchronous) network of sensors employing directional …

Wireless Sensor Networks Due to its potential applications in various situations such as
battlefield, emergency relief, environment monitoring, and so on, wireless sensor networks …

Given a set of points in the plane, we want to establish a connection network between these
points that consists of several disjoint layers. Motivated by sensor networks, we want that …

This paper concerns wireless sensor networks (WSNs) of which each node is equipped with
k≥ 1 directional antennas having beam-width θ∈(0, 2π). The sum φ k of the beam-widths of …

In this paper, we investigate the Antenna Orientation (AO) and Antenna Orientation and
Power Assignment (AOPA) problems concerning symmetric connectivity in Directional …
