Projekt CoMobility ma na celu identyfikację czynników, które mogą skłonić ludzi do zmiany zachowań transportowych. Umożliwi to wypracowanie narzędzi pozwalających miastom planować i wprowadzać rozwiązania zrównoważonego transportu i aktywnej mobilności. Jest to bardzo istotna kwestia, biorąc pod uwagę, że liczba samochodów na 1000 mieszkańców w Polsce jest jedną z najwyższych w Europie. Ma to znaczący wpływ na środowisko, zdrowie i kondycję fizyczną ludności, a także warunki funkcjonowania miast. Dążąc do popularyzacji aktywnej mobilności i ograniczenia „kultu auta”, odwołujemy się do rozwiązań stosowanych w różnych miastach Europy i Polski.

The CoMobility project aims to identify the factors that can encourage people to change their transport behaviour. This will enable the development of tools allowing cities to plan and implement sustainable transport and active mobility solutions. This is a very important issue given that the number of cars per 1,000 inhabitants in Poland is one of the highest in Europe. This has a significant impact on the environment, the health and fitness of the population, as well as on the operating conditions of cities. In an effort to popularise active mobility and reduce the “cult of the car”, we refer to solutions applied in various European and Polish cities.

With growing popularity of unmanned aerial vehicles (UAVs), the importance of flying ad-hoc networks (FANETs) is enhanced by such applications as 4K video recording, communications in search and rescue missions and goods deliveries, to name just a few. This, in turn, stimulates research on different topologies of networks existing between UAVs, with studies in this field being essential to improving performance of such networks. Several problems must be solved to effectively use UAVs in order to offer stable and reliable massive data transmission capabilities, taking into consideration quickly changing FANET topologies, types of routing, security issues, etc. In this paper, a comprehensive evaluation of FANETs used by UAVs is presented in terms of communication network challenges, data types, mobility models and standards applied in order to achieve best performance. The evaluation presented herein covers such areas as data throughput, retransmission attempts and delay.

Praca dotyczy zagadnień związanych z symulacją mobilnych sieci ad-hoc (MANET). Sieci tego typy odgrywają coraz większą rolę w zastosowaniach cywilnych i wojskowych, w tym w monitorowaniu środowiska i wspieraniu akcji ratunkowych. Zakładając możliwość sterowania ruchem urządzeń tworzących sieć, autor zaproponował algorytm i przedstawił wyniki symulacji formowania mobilnej sieci ad-hoc z wykorzystaniem modelu ruchu węzłów PFM.

This article addresses issues associated with simulation and application of wireless, mobile, and ad-hoc networks (MANETs). Mobile self-organizing ad hoc networks can enhance the capability to coordinate the emergency actions as well as monitor contaminated areas, explore unmanned space, inspect and control working environments. Modeling and simulation are widely used in the design and development of wireless ad hoc networks. The focus is on wireless transission and mobility models. A novel algorithm for wireless sensor network deployment is introduced.

This paper addresses issues concerned with design and managing of monitoring systems comprised of mobile wireless sensing devices (MANETs). The authors focus on self-organizing, cooperative and coherent networks that maintain a continuous communication with a central operator and adopt to changes in an unknown environment to achieve a given goal. The attention is focused on the development of MANET for heavy gas clouds detection and its boundary estimating and tracking. Two strategies for constructing the MANET are described, in which sensors explore the region of interest to detect the gas cloud, create temporary network topology and finally, cover the cloud boundary, and track the moving cloud. The utility and efficiency of the proposed strategies has been justified through simulation experiments.

In this paper, we investigate the impact of mobility on the performance of multi-hop wireless ad hoc and sensor networks. We introduced some models of mobility in these networks and studied their behavior in realistic situations. It concerns the basic relationship between link length and message transmission. Additionally, we take into consideration the probability of successful transmission in an interference limited channel when fading is modeled as Rayleigha block fading. Our mobility models are verified by an accurate description and simulation of the behavior of mobile sensor and ad hoc networks.

W pracy zbadano wpływ ruchu na wydajność wieloetapowych bezprzewodowych sieci ad hoc oraz sensorowych. Wprowadzono pewne modele ruchu w tych sieciach, a także zbadano ich zachowanie w realistycznych sytuacjach. Artykuł rozważa podstawowe zależności pomiędzy długością łącza radiowego a transmisją kominikatu. Rozważono w nim prawdopodobieństwo poprawnej transmisji w przypadku krótkookresowych zaników z funkcją gęstości prawdopodobieństwa obwiedni sygnału opisywanego rozkładem Rayleigha. Dla weryfikacji modeli ruchu przeprowadzono badania symulacyjne zachowania ruchomych sieci sensorowych i ad hoc.

In scenarios of military operations and catastrophes - even when there is no infrastructure available or left - there is a need for communication. Due to the specific context the communication systems used in these tactical scenarios need to be as reliable as possible. Thus, the performance of these systems has to be evaluated. Beside field-tests, computer simulations are an interesting alternative concerning costs, scalability, etc. Results of simulative performance evaluation strongly depend on the models used. Since tactical networks consist of, or, at least, contain mobile devices, the mobility model used has a decisive impact. However, in common performance evaluations mainly simple random-based models are used. In the paper we will provide classification and survey of existing mobility models. Furthermore, we will review these models concerning the requirements for tactical scenarios.
