Throughput-oriented Power Allocation Scheme Based on Convex Optimization for Cache-enabled FiWi Access Network in 5G IoT Scenario

This paper presents an energy-saving wireless power allocation scheme based on convex optimization (PA-CO) in cache-enabled Fiber-Wireless (FiWi) access networks. Experiments indicate that the proposed PA-CO improves the global throughput when confronted with large-scale access terminal sets in 5G IoT scenario, while remaining total power consumption to a low level.
