WiFi AP with ad-hoc functionality and posibility for use in enviroment with an explosive atmosphere
Vrlík, Martin ; Hanák, Pavel (referee) ; Šteffan, Pavel (advisor)
This work explains development of device which is being designed for aplication in an environment with an explosive atmosphere. In each chapter there will be explained result and step by step progress of developing this device. Then there will be description of function and used parts in completed device. At the begining there will be parameters which we have to acomplish to ensure the ability of device to be used in explosive atmosphere. At the end there will be described a selection of suitable operating system.
Wireless communication module in 868 MHz band with MESH network support
Uhlíř, Marcel ; Fedra, Zbyněk (referee) ; Povalač, Aleš (advisor)
This thesis deals with design of a wireless communication module that allows communication in the unlicensed band at the frequency of 868 MHz. The designed module can be easily implemented in various types of embedded devices using SMT technology. This communication module consists of a low-power radio frequency transmitted, balancing element, impedance matching, radio antenna and electromagnetic shielding. Communication between the embedded device and the wireless communication module is realized using the SPI interface and configurable GPIOs. Part of this work is the proposed firmware library, which operates the wireless communication module and allows communication in peer-to-peer mode and in MESH network mode. A procedure for its creation and management is created as part of the MESH network. The use of this work is directed to the field of control and sensor systems with application in automation.
Mobile IP in MANETs
Raška, Martin ; Hošek, Jiří (referee) ; Skořepa, Michal (advisor)
This thesis discuss about the problem with mobility of stations in IP networks, concretely protocol Mobile IP and about the problems with this protocol in MANET networks, with the scope on Motorola MESH. First part is about design integration of protocol Mobile IP in this networks with usage Tropos 5210 MetroMesh routers and Cisco components (router, switch) to design and configure wireless MESH network, than connect this network with Cisco components and try to implement Mobile IP into this network. Second part is about design and configure wireless network from Cisco Wireless Access Points and about succesfully implementation of Mobile IP protocol into this network. In the last part is some tests of the function and quality of this topology.
Dynamic Mesh Network Implemented in Micropython on Top of ESP-NOW Protocol
Šesták, Jindřich ; Hujňák, Ondřej (referee) ; Malinka, Kamil (advisor)
Cílem této práce je vytvořit fungující dynamickou mesh síť na ESP32 microkontrolerech pro využití v IoT a senzorových sítích. Mesh síť se skládá z několika uzlů mezi sebou propojených do stromové struktury a je schopna se vypořádat i z pádem kteréholiv z uzlů. To je zajištěno vytvořením nového mesh řešení, které je schopno fungovat s připojením k Internetu i bez připojení. Použití MicroPython umožňuje asynchronní zpracování neblokujícím způsobem. Projekt je postaven pomocí dvou komunikačních protokolů, proprietárního ESP-NOW a běžné WiFi komunikace. Řešení přináší možnosti rychlého vývoje mesh aplikací, ale je silně limitováno pamětí mikrokontrolerů. Funkčnost řešení byla otestovaná pomocí vytvořené demo aplikace se sadou třech testovacích scénářů pro domácí použití.
