研究目的
To propose a passive wavelength division multiplexing based fronthaul architecture for heterogeneous cellular networking and a threshold based on/off algorithm for micro cells to save energy.
研究成果
The proposed passive WDM based fronthaul architecture and micro-cell on/off algorithm significantly reduce energy consumption in heterogeneous cellular networks. The study also highlights the impact of different functional split options, OT rates, and the number of neighboring cells on energy savings.
研究不足
The study focuses on simulation results and may not account for all real-world variables in heterogeneous cellular networks. The proposed algorithm's performance in dynamic environments with varying traffic loads needs further investigation.
