Diplomová práce “Výkonnost směrování v Ad-hoc sítích” se zabývá problematikou směrování v sítích VANET (Vehicular ad-hoc network), které jsou založené na topologii Ad-hoc sítí. Práce obsahuje charakteristické definice a teoretický popis jednotlivých vlastností dané sítě, ze kterých vychází praktická část. V další části se pojednává o jednotlivých p...
Les réseaux mobiles "Ad hoc" sont des réseaux formés de façon dynamique grâce à la coopération d'un ensemble arbitraire de noeuds indépendants qui s'organisent automatiquement de façon à être rapidement déployables, et qui doivent pouvoir s'adapter aux différents mouvements pouvant intervenir au sein des noeuds mobiles. Ces réseaux ne peuvent pas ê...
The modeling of wireless networks with stochastic geometry has become popular in the recent decades. By means of point processes, the positions of wireless infrastructure and users are represented with the aim of computing metrics of interest like capacity, routing delay, broadcast time, etc. This has been done successfully for technologies such as...
[EN] The use of multicopters is spreading rapidly due to their wide scope of application. This means that, as time goes by, the risk of collision between these devices significantly increases. Moreover, solutions where swarms of multicopters are used to solve more complex problems through cooperation are being proposed. Both cases require multicopt...

In MAC protocols of wireless ad hoc networks, there may be collisions due to traffic load and it results in more energy consumption, delay and reduces throughput. In order to overcome these issues, in this paper we propose a game theory and fuzzy based back off algorithm for MAC Protocol for multi traffic flows in wireless ad hoc networks. When a n...

Multi-hop relaying combined with scarcity of wireless resources in ad-hoc networks can deteriorate the quality of service. As a result, one of the major challenges in video streaming over ad-hoc networks is enhancing users’ experience and network utilization. The emergence of scalable video coding standard enables smooth adaptation of video quality...
[ES] El uso de multicópteros se está extendiendo rápidamente debido a los muchos campos de aplicación que tienen, por lo que cada vez más hay riegos de colisión entre estos aparatos. Además, se están empezando a proponer soluciones donde enjambres de multicópteros logren solucionar problemas más complejos mediante cooperación. Ambos casos requieren...
Aeronautical Ad-hoc NETworks (AANETs) have been studied and could be proposed as an complementary communication system for civil aviation. Several routing algorithm have been proposed and assessed through simulation, but there is a lack of evaluation in realistic conditions, especially regarding the access layer. In this paper we propose to use Ran...
The internet of things (IoT) has been attracting growing attention in recent years. As one potential technology used for IoT sensor network, Bluetooth Low Engery (BLE) is becoming one of the most anticipated solutions to establish IoT networks. Whilst BLE based IoT devices are becoming increasingly popular, security becomes an unavoidable concern n...
