1. 1. IoT Latency and Power consumption : Measuring the performance impact of MQTT and CoAP

   University essay from Högskolan i Jönköping/JTH, Datateknik och informatik

   Author : Alexander Lagerqvist; Tejas Lakshminarayana; [2018]
   Keywords : Internet of things; IoT; Wireless sensor networks; WSN; Constrained devices; MQTT; CoAP; Latency; Power consumption; Experiment;

   Abstract : The purpose of this thesis is to investigate the impact on latency and power consumption of certain usage environments for selected communication protocols that have been designed for resource constrained usage. The research questions in this thesis is based on the findings in Lindén report “A latency comparison of IoT protocols in MES” and seeks to answer the following: ”How does MQTT impact the latency and power consumption on a constrained device?” ”How does CoAP impact the latency and power consumption on a constrained device?” ”How does usage environment influence the latency for MQTT and CoAP?” This thesis only seeks to explore concepts and usage environments related to wireless sensor networks, internet of things and constrained devices.
