There are some underwater areas with high ecological interest that should be monitored.
Posidonia and seagrasses exert considerable work in protecting the coastline from erosion …

This paper provides a general framework to model and optimize lifetime maximization
problems in wireless sensor networks with sensors having specialized capabilities like the …

This paper is devoted to the construction of regular min-density plane coverings with ellipses
of one, two and three types. This problem is relevant, for example, to power-efficient surface …

The article considers models for monitoring a band with a preset width using sensor
networks shaped as disc covers. Every cover disc is a centred sensor operation area. The …

Исследуются регулярные покрытия плоскости кругами. В таких покрытиях плоскость
разбивается на правильные многоугольные плитки и все плитки покрываются …

The energy of sensor nodes in wireless sensor networks (WSNs) is limited and difficult to be
replenished, therefore energy conservation and energy management play a very important …

В данной работе рассматриваются задачи построения наименее плотных регулярных
покрытий плоскости кругами, эллипсами и секторами, которые возникают в контексте …

We study the problem of constructing a least dense regular cover of a strip with identical
sectors which arises in designing wireless sensor networks. Three models are proposed …

In the regular covers, a region in the plane is split into the equal regular polygons (tiles), and
all the tiles are covered equally with some geometric figures. In this paper, a tile is an …

In this paper, we analyze CSMA-CA access for interconnection of IEEE 802.15. 4 beacon
enabled network clusters using ordinary network nodes as bridge nodes. Bridge design …
