Abstract The implementation of machine-to-machine (M2M) communications in fifth-generation (5G) cellular networks can facilitate with several benefits like enhancement of bandwidth utilization, accommodating large number of users and decreasing traffic load on evolved node B (eNB). Integration of location information of unknown machine in communication mode selection mechanism is the key feature of this research. In this paper, a distance based communication mode selection mechanism using non-orthogonal resource sharing scheme is adopted in the proposed system model. Under the proposed mechanism, the expressions of throughput and RBs utilization policy are derived, which are the key parameters to evaluate the performance in the proposed network. Depending on the mode selection condition, such as threshold distance and threshold SINR between M2M users and regular cellular users, a UE can automatically choose its communication mode in the network. It is supposed that selection of mode before data transfer can improve the system performance. On the other hand, designing of efficient distance assisted proposed resource blocks (RBs) utilization policy reduces the traffic load on the eNB. Extensive simulations are carried out for evaluating the performance of the proposed mechanisms. The system performance is compared with various changeable parameters, such as throughput, mode selection threshold SINR, threshold distance and RBs. Besides, the proposed mechanism provides better network performance as well as reduces the traffic load in the proposed network.

1 Introduction Machine-to-machine (M2M) communications refer to a communication technique that let machines to talk directly with one another without traversing any evolved node B (eNB) [1–4]. M2M communications are considered as an auspicious concept which have gained rising research attention in current years for numerous advantages upon traditional cellular networks. This promising technology can accommodate a large number of users by sharing spectrum resources that results enhancement of the system throughput. As the one hop based direct communication does not traverse the eNB, this technique increases spectral efficiency and also reduces traffic load on eNB. Besides, other conveniences of M2M communications include
