1. Jämförelse av OPS, MQTT och DDS med avseende på fördröjningstid och throughput
Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : In this study a comparison of the publish-subscribe communication protocols OPS, MQTT and DDS were conducted. The implementation used for DDS was fastDDS and the client library Paho Eclipse MQTT C++ was used for MQTT with the broker implementation Eclipse Mosquitto. LÄS MER
2. Performance of State Distributing Message-Oriented Middleware Systems Using Publish-Subscribe
Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : 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.

3. Comparing the scalability of MQTT and WebSocket communication protocols using Amazon Web Services
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This study compares the scalability of two popular communication protocols within IoT, MQTT and WebSocket. The scalability comparison of the protocols is performed using a publish-subscribe pattern. EMQX is used to run the MQTT message broker, and Socket.IO is used for theWebSocket message broker. LÄS MER
4. Towards reducing bandwidth consumption in publish/subscribe systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Efficient data collection is one of the key research areas for 5G and beyond, since it can reduce the network burden of transferring massive data for various data analytics and machine learning applications. Specifically, 5G offers great support for massive deployment of IoT devices, and the number of IoT devices is exploding. LÄS MER
5. Using the Mosquitto implementation in an embedded environment
Master-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : An essential challenge of the Internet of Things is how to share data between embedded systems. One way of doing this is with the protocol MQTT. MQTT is a message distribution protocol which uses a publish and subscribe method to share data. The company Fältcom uses an implementation of MQTT called Mosquitto to distribute data between their units. LÄS MER
