Nowadays mobile devices are growing in number and computational resources. Devices capable of storing gigabytes of digital content are becoming ubiquitous, making them an ideal platform for peer-to-peer content delivery and sharing. However, the always on communication patterns of P2P networks are not a natural fit for energy-constrained mobile devices. This paper performs a detailed study of energy consumption of a structured P2P overlay on a PDA device. Using actual energy measurements, the paper presents energy consumption results for different type of operations in P2P overlays. Based on these observations, the paper implements an approach to improve energy conservation on P2P protocols and show some promising preliminary results.
