Abstract

This master’s thesis investigates and compares the performances of LwM2M and MQTT operating in LTE-M and NB-IoT. The experiments consider the traffic-overthe-air generated by the two IoT protocols, delivering information about the packets captured and the number of bytes exchanged. Moreover, the average energy consumption analysis describes how LwM2M and MQTT may influence devices. Also, the work explains how security authentication methods as well as cellular networks’ properties may impact on the protocols’ efficiency. Finally, the results’ evaluation draws a conclusion about the impact of LwM2M of MQTT in cIoT and how these perform compared to each other. Keywords: LwM2M, MQTT, LTE-M, NB-IoT, cIoT, energy consumption, traffic-over the-air, LPWAN, IoT
