Abstract Machine-to-Machine (M2M) communication is considered as a promising technology in fifth-generation (5G) cellular networks to reduce the power consumption and improve energy efficiency. To achieve these benefits, identification of unknown machine location is crucial for mitigating interference. Therefore, this paper proposes a location-aware communication mode selection based power control mechanism for reducing interference in M2M communications over cellular networks. The proposed mechanism depends on the threshold distance while communicating among M2M pair. Consequently, user equipment (UE) selects the proper communication mode in the proposed mechanism. Resource allocation between the M2M UEs (MUEs) and cellular UEs (CUEs) that share the resources in both orthogonal and non-orthogonal ways are analyzed for different modes. A water filling algorithm and Lagrange decomposition scheme based power optimization process are adopted for allocating the proper optimal transmit power to each UE in the proposed mechanism. Simulation results are compared with the non-orthogonal and orthogonal resource sharing scheme based proposed mechanism which shows that the orthogonal resource sharing scheme provides better system performance in the proposed network.

在蜂窝网络上的 M2M 通信中减轻干扰的位置感知功率控制机制

摘要 机器对机器（M2M）通信被认为是第五代（5G）蜂窝网络中一种很有前途的技术，可以降低功耗和提高能源效率。为了实现这些好处，识别未知机器位置对于减轻干扰至关重要。因此，本文提出了一种基于位置感知通信模式选择的功率控制机制，以减少蜂窝网络上 M2M 通信中的干扰。所提出的机制取决于 M2M 对之间通信时的阈值距离。因此，用户设备（UE）在所提出的机制中选择合适的通信模式。针对不同模式分析了以正交和非正交方式共享资源的 M2M UE (MUE) 和蜂窝 UE (CUE) 之间的资源分配。在所提出的机制中，采用注水算法和基于拉格朗日分解方案的功率优化过程来为每个UE分配合适的最优发射功率。仿真结果与基于所提出机制的非正交和正交资源共享方案进行了比较，表明正交资源共享方案在所提出的网络中提供了更好的系统性能。
