Traffic-Driven Power Saving in Operational 3G Cellular NetworksSpeaker: Abhishek Roy – San Francisco, United States
Topic(s): Networks and Communications
AbstractBase stations (BSes) in the 3G cellular networks are not energy proportional with respect to their carried traffic load. Our mea- surements show that 3G traffic exhibits high fluctuations both in time and over space, thus incurring energy waste. In this paper, we propose a profile-based approach to green cellular infrastructure. In this lecture we discuss profiling BS traffic and approximating network-wide energy proportionality using non-load-adaptive BSes. The key is to leverage temporal-spatial traffic diversity and node deployment heterogeneity, leading to power off under-utilized BSes under light traffic. Evaluation on four regional 3G networks shows that this simple scheme yields up to 53% energy savings in a dense large city and 23% in a sparse, mid-sized city.
