  1. 1. LP_MQTT - A Low-Power IoT Messaging Protocol Based on MQTT Standard

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Anchu Antony; Deepthi Myladi Kelambath; [2024]
    Nyckelord :;

    Sammanfattning : In the Internet of Things (IoT) era, the MQTT Protocol played a bigpart in increasing the flow of uninterrupted communication betweenconnected devices. With its functioning being on the publish/subscribe messaging system and having a central broker framework, MQTTconsidering its lightweight functionality, played a very vital role inIoT connectivity.

  4. 3. Performance of State Distributing Message-Oriented Middleware Systems Using Publish-Subscribe

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Robin Edlund; Johannes Kettu; [2023]
    Nyckelord :Message-oriented middleware; publish-subscribe; topic; tactical simulator; flight simulator; Meddelandeorienterad mellanprogramvara; publish-subscribe; topic; taktisk simulator; flygsimulator;

    Sammanfattning : Distributed simulations require efficient communication to represent complex scenarios, which presents a great challenge. This paper investigates the use of message-oriented middleware (MOM) to address this challenge by integrating the flight simulator X-Plane with the tactical simulator TACSI and evaluating the performance of different data transfer approaches.
