In this paper, the problem of resource allocation for IoT devices in the NB-IoT network is studied where the NB-IoT eNodeB (NB-IoT eNB) in the network allocates the radio resource for enabling the uplink communication. The key challenge of the resource allocation problem is to ensure not only fairness but also efficiency in terms of allocating radio resource to the IoT devices considering data correlation. Therefore, in this paper, we exploit the spatial correlation of the NB-IoT devices and propose a cooperative game approach, bankruptcy game, for radio resource allocation for Narrowband Internet of Things (NB-IoT). The proposed game framework is able to provide both efficiency and fairness while allocating the radio resource for a massive number of IoT devices. In the simulation, we show that the proposed approach can significantly improve the radio resource allocation efficiency compared to the greedy approach and also the effect of correlation in the performance gain of the proposed method under different assumptions.
