突发性数据传输易导致3G网络工作模式从低功耗状态向高功耗状态迁移,状态切换加剧能耗开销.本文对移动终端网络通信行为进行分析,提出移动终端下3G网络低功耗延迟唤醒策略.该策略对网络数据进行延时敏感性划分,并据此进行不同时间的延时传输,延迟3G网络唤醒时间达到降耗目的.仿真实验表明,策略有效降低系统功耗,具有较强的可行性.
The burst data transfer will lead to 3G migration from the low-power state to high-power state, and frequent switching exacerbates the energy consumption. We analyze 3G network communication behavior and give a low-power strategy based on delayed awakening 3G network for smartphone. The strategy classifies packages according to the delay-sensitivity, and delays sending packet for different intervals so as to reduce the energy consumption. Simulation results show that the proposed mechanism effectively reduces the power consumption of the system and has the strong feasibility.
