在本文中，调度和发射功率控制的LTE网络中部署的电池驱动的设备，以最大限度地减少能源消耗。为了使大量的机器型用户的有效调度，提出了一种新的分布式方案，让机器节点形成本地集群和通信的基站通过簇头。然后，在LTE网络中的上行链路调度和功率控制进行了介绍和寿命感知的解决方案进行了研究，用于簇头和基站之间的通信。除了精确解，低复杂度的次优解决方案，在这项工作中，可以实现接近最优的性能与低得多的计算复杂度。性能评估表明，网络的生命周期显着延长使用所提出的协议。
In this paper the scheduling and transmit power control are investigated to minimize the energy consumption for battery-driven devices deployed in LTE networks. To enable efficient scheduling for a massive number of machine-type subscribers, a novel distributed scheme is proposed to let machine nodes form local clusters and communicate with the base-station through the cluster-heads. Then, uplink scheduling and power control in LTE networks are introduced and lifetime-aware solutions are investigated to be used for the communication between cluster-heads and the base-station. Beside the exact solutions, low-complexity suboptimal solutions are presented in this work which can achieve near optimal performance with much lower computational complexity. The performance evaluation shows that the network lifetime is significantly extended using the proposed protocols.
