One of the most pervasive technologies in the world –especially for the developing communities– comes in the form of mobile communication devices and associated services. For billions of people across the world, primary access to communication networks, including Internet, comes through their mobile phones – not from personal computers or fixed landlines telephony. This pervasive communication technology is on its way to fundamentally change social networking in local communities and dramatically improving education for remote schools. The same pervasive technology combined with sensor technologies is revolutionizing fieldwork in health care and agriculture for rural areas. In addition for the 3B people in the world that do not have a bank account pervasiveness of the mobile devices allows widening financial services like never before. These developments will lead to an increase in information and communication traffic, and by some predictions the communication industry’s contribution to the global carbon footprint is forecast to double over the next ten years. While incremental approaches to reducing energy consumption are possible, they will ultimately fail to keep pace. We are interested in a more ambitious and holistic solution that is required to achieve targets in the long term and address the growing demand for energy driven by dramatic increases in the number of users, new usage patterns, and the advent of machine-to-machine communication from sensor-based services.
In this talk we will look at research in holistic energy management for the building blocks of these global communication systems from nanosensing architectures of future devices to the system software of the distributed clouds. We will present some of the early ground-breaking research on assessing the energy consumption of mobile systems based on real application usage patterns (VOIP, messaging, browsing, sensing) and demonstrate some initial solutions that can achieve 30-90% savings on the energy consumption. We conclude by outlining interesting (multi-disciplinary) research challenges in this area prompted by these observations.
