Abstract :
This paper introduces a novel quality-oriented cross-layer energy-efficient data communication solution (Q-PASTE) for mobile devices, with two components at different network layers. First component, the Packet/ApplicaTion manager (PAT) is deployed at the application layer of both service gateway and client host. The gateway level PAT shapes traffic into bursts to reduce the wireless transceiver´s duty cycle. The client-side PAT monitors each active session and informs the Medium Access Control (MAC) layer about their traffic-related behavior. The second component, the Slow sTart Exponential and Linear Algorithm (STELA), deployed at MAC layer, adaptively adjusts the sleep/wake-up behavior of mobile device wireless interfaces in order to reduce energy consumption while also maintaining high Quality of Service (QoS) levels. Both mathematical analysis and simulation-based modeling and testing have been performed to evaluate Q-PASTE performance. Comparative results have shown significant energy saving achieved when using Q-PASTE, without compromising content delivery performance.
