Saving Energy in Mobile Devices for On-Demand Multimedia Streaming -- A Cross-Layer Approach
This addresses energy efficiency for mobile device users during streaming, representing a strong specific gain rather than a broad paradigm shift.
The paper tackled the problem of high energy consumption during multimedia streaming on mobile devices by proposing EStreamer, a cross-layer system that improves battery lifetime by 3x over Wi-Fi, 1.5x over 3G, and 2x over 4G.
This paper proposes a novel energy-efficient multimedia delivery system called EStreamer. First, we study the relationship between buffer size at the client, burst-shaped TCP-based multimedia traffic, and energy consumption of wireless network interfaces in smartphones. Based on the study, we design and implement EStreamer for constant bit rate and rate-adaptive streaming. EStreamer can improve battery lifetime by 3x, 1.5x and 2x while streaming over Wi-Fi, 3G and 4G respectively.
