This project explores the design of green cellular network architectures and algorithms to reduce energy consumption. A major consumer of energy in cellular networks is the operation of the base stations. Most base stations are deployed and operated continuously based on peak traffic estimates. Intuitively, it saves energy to judiciously "scale back" un-utilized and under-utilized base stations during off-peak times. The remaining base stations must adapt accordingly so that the required coverage is maintained.The PIs propose a dynamically adaptive cellular network where the cell size and capacity of the base stations are dynamically reconfigured based on the current user locations and Quality of Service (QoS) demands of the applications. Modeling of the network power consumption based on the network topography, followed by optimization of the topography is the key to this problem. The project will involve student participation at all stages through suitably designed projects. The results of the research will be disseminated through professional journals and conference proceedings and also through industry forums and workshops. Furthermore, the project addresses one of the most pressing issues of today, namely, reducing the carbon footprint of the cellular network. Radical new designs for the network have the potential to spur economic development, create jobs and forge stronger communities.

本项目探讨绿色蜂窝网络架构和算法的设计，以减少能源消耗。蜂窝网络中能量的主要消耗者是基站的操作。大多数基站是基于峰值业务估计来连续部署和操作的。直观地说，在非高峰时间明智地“缩减”未利用和未充分利用的基站可以节省能量。PI提出了一种动态自适应蜂窝网络，其中基站的小区大小和容量基于当前用户位置和应用的服务质量（QoS）需求而动态地重新配置。在网络拓扑的基础上对网络功耗进行建模，进而对拓扑进行优化是解决这一问题的关键。该项目将通过适当设计的项目在各个阶段涉及学生的参与。研究结果将通过专业期刊和会议记录以及行业论坛和讲习班传播。此外，该项目还解决了当今最紧迫的问题之一，即减少蜂窝网络的碳足迹。激进的新网络设计有可能刺激经济发展，创造就业机会和打造更强大的社区。
