Consider a set S of nodes in the plane such that the unit-disk graph G (S) spanning all
nodes is connected. Each node in S is equipped with a directional antenna with beam-width …

Because of limited battery equipped on each sensor, power consumption is one of the
crucial issues in wireless sensor networks (WSNs). It therefore has been the focus of many …

Topology control is important for heterogeneous sensor networks in order to minimize the
total network power consumption under the constraint that all sensor nodes' connectivity …

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 study the Antenna Orientation (AO) problem concerning symmetric
connectivity in Directional Wireless Sensor Networks. We are given a set of nodes each of …

Consider a set S of nodes in the plane such that the unit-disk graph G (S) spanning all

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

Recent advances in wireless sensor networks (WSNs) allow directional antennas to be used
instead of omni-directional antennas. However, the problem of maintaining (symmetric) …

Minimizing the total energy consumed by wireless sensor network (WSN) is a significant
problem, since the sensor nodes are attached with a small battery of restricted capacity. In a …
