Massive Machine Type Communication and cellular Internet of Things based on Narrowband IoT
3GPP Release 13 NB-IoT has triggered attention of research and operator communities, as one of the most appealing enablers of massive Machine Type Communication (mMTC) and cellular Internet of Things (cIoT). NB-IoT specific features, together with peculiarities of the implied novel and complex scenarios that involve an ever-increasing number of communicating devices, require extensive analyses and advanced testing, i.e. field trials and ad-hoc simulation experiments. To this aim, a NB-IoT simulator, based on the upgrade of the ns-3 LTE suite, is proposed and will be applied to a case study of NB-IoT network-wide analysis. Configuration of NB-IoT procedures of network access, coverage level estimate, and coverage enhancement via signal repetitions, together with a planned resource distribution with coexisting LTE/LTE-A systems, will be analysed in order to provide performance in terms of network and device efficiency.
