在本文中，我们研究了多个中继的优化规划和部署问题，以支持物联网（IoT）设备的节能上行传输。提出了一种以网络总能耗最小为目标的中继位置优化方法。同时，对物联网设备的上行发射功率和设备-中继-信道关联进行联合优化，以满足物联网设备的QoS要求。建立了一个混合整数线性规划（MILP）问题，以求得最优解。我们还设计了一个低复杂度的遗传算法来提供问题的次优解。
In this paper, we investigate the problem of optimal planning and deployment of multiple relays to support energy- efficient uplink transmissions of Internet of Things (IoT) devices. A novel approach is proposed to optimize the relay locations with the objective of minimizing the total energy consumption of the network. In addition, the uplink transmit power of IoT devices and the device-relay-channel association are jointly optimized to meet the QoS requirement of IoT devices. A mixed-integer linear programming (MILP) problem is formulated to obtain the optimal solution. We also design a low-complexity genetic algorithm to provide a sub-optimal solution to the problem.
