E2-DLNA: An Improved Energy-Efficiency Mechanism for DLNA
As the explosive growth of mobile networks, green mobile networks have been studied extensively. DLNA protocol, widely used in smart home, does not take any consideration for power saving. In this paper, we propose an energy-efficient mechanism for DLNA (E 2 -DLNA), which can achieve balance between QoS provision and energy efficiency. The core network condition estimation algorithm TES used in E 2 -DLNA can help Mobile Handheld Devices (MHD) adjust its packets-sending strategy according to estimated network condition. In this way, MHDs can dramatically reduce the unnecessary multicasting messages. Our experimental results show the effectiveness of E 2 -DLNA. Energy consumption can be reduced 10-30%
