“…Time-critical applications, such as SAR ones, can highly benefit by using unmanned aerial vehicles (UAVs) or UAVswarms with a flying network attached to determine the PV's location [16]. Some cluttered scenarios, such as lush forests, make it difficult for drones to move without colliding.…”

“…Among the missions of UAVs and unmanned ground vehicles (UGVs) is to act as robotic platforms as a means of transport to bring a mobile network infrastructure to places where they do not exist. A flying network for emergencies is proposed in [16], where UAVs act as WiFi Access Points (AP), always ready to capture any signals from clients (usually smartphones carried by the PVs). However, there is a big dependence of the positioning error on the number of received signals and on the relative accuracy of distance measurement.…”

In the field of rescue robotics, data collection about the environment and efficient communications are fundamental for the success of search and rescue missions. Digitalization provides new ways of detecting and localizing potential victims via the wireless devices carried by the users. Nowadays, the number of personal Bluetooth low energy wearables in use (smartbands, smartwatches, earbuds...) increases constantly, being a yet-to-be-exploited personal radio frequency beacon in the case of an emergency, where the user may not be localized and unconscious. In this paper, the results of experimental tests of a Bluetooth low energy based detection system ported by terrestrial and aerial robots are provided, in order to test the feasibility of such system for the localization of the victims in unknown complex disaster areas. The results show that the tested devices can be reliably detected up to 15 meters away when using transmission power values typical of a smartphone, while being able to detect even lightly burdened devices. These results support the idea of developing an algorithm for the delimitation of areas of interest for the search and rescue groups, influencing the routes followed by the robot with the objective of exploring the detected devices area in the search of victims.

“…Планирование современных беспроводных локальных вычислительных сетей (БЛВС) ячеистой архитектуры трудно представить без решения задачи частотно-территориального планирования. Это в равной мере справедливо для различных БЛВС -как стационарных, так и реализуемых, например, с применением беспилотных летательных аппаратов [1,2]. В особенности это касается сетей на базе стандарта IEEE 802.11 [3], в которых выбор частотной сетки во многом зависит от администратора инфраструктуры.…”

IEEE 802.11 wireless networks design process is impossible without a correct choice of a channel plan, i.e. a set of channels of a given type. This is especially important because channel planning of a distributed network heavily depends on the network designer’s and administrator’s decisions. Additionally, the central frequencies of the channels provided by the standard do not mean that the channels are non-overlapping. However, considering the coverage of a flat area as a plane tessellation by coverage areas of access points, for a particular regular structure geometry, it is necessary to choose the best channel planning solution among the possible ones. To do this, it is required to consider practically applicable channel planning cases, which use different numbers of channels, as a plane tessellation problem, also taking into account the overlapping of their spectral masks. This paper considers channel planning of IEEE 802.11 networks as a plane tessellation with regular structures and proposes a model that takes into account the effects of adjacent-channel interference, provides evaluation criteria, and thus is applicable to select the best channel configuration for the corresponding regular structure.
