Abstract

In this paper, we propose a scheme for double-layered mobile P2P systems that enhances energy efficiency by modifying PSM(Power Saving Mode) defined in 802.11. The proposed scheme lengthens the beacon interval adaptively and adopts a known power saving scheme for more power saving. The experimental results showed that the proposed scheme improved 58.3% in terms of the average energy saving and 10% in terms of the average success ratio for file searches over the system with the standard PSM.
