Abstract
A narrow-band system introduced in Release 13 of 3GPP has recently gain momentum to support a range of IoT use-cases. Narrowband-Internet of Things (NB-IoT) comes with low-cost devices characterized by extremely low power consumption, offering a battery life of more than 10 years, and broad radio coverage to target tens of kilometers, but on the cost of low data rate and higher end-to-end latency. NB-IoT can be deployed in three different modes of operation; stand-alone, in-band, and within the guard-band of existing LTE carrier. In this paper, a hybrid network model embracing both NB-IoT and D2D technologies has been introduced. we first present an analytical framework to derive analytical rate expressions for D2D in NB-IoT networks. Then, the performance gains of network model are investigated through numerical evaluations that demonstrate the superiority of proposed model over the traditional NB-IoT network.
