A narrowband IoT (NB-IoT) device’s battery life is vibrant for the future evolution of networks being wireless. The efficiency of energy for cooperative cellular NB-IoT networks is explored in this paper. In this context, the three-hop assignment problem is proposed; the theory of a double auction is used for its construction. The three-hop assignment aims to increase the battery life of a cell edge narrowband IoT users (CENUs) along with concentrating on energy-efficiency enhancement. In the proposed model, to get maximum battery life, the transmission power of NB-IoT user (NU) is taken into consideration and is decreased to the possible lowest magnitude. Also, to increase the battery life of CENU, an energy-efficient narrowband IoT user–maximum weight matching method (EENU–MWM) is recommended. Lastly, EENU–MWM performance is assessed in terms of capacity, EE, transmission time, which demonstrates that EENU–MWM can significantly enhance the efficiency of the cooperative NB-IoT cellular network. |
