Energy Aspects of Peer Cooperation Measurements with a Mobile DHT System
Imre Kelényi, Jukka K. Nurminen · 2008
Distributed Hash Tables (DHTs) are widely studied from the fixed computer point of view, but very little research has been done on the performance of mobile clients. We have implemented a DHT client for mobile phones and carried out energy measurements to analyze the power profile of the application. By connecting to a widely deployed DHT, we were able to observe how mobile clients perform in a million user environment. We show that using a mobile phone as a full-peer is feasible only for a couple of hours due to the high power consumption. We also define the client-only mode that allows mobile nodes to use the services of the DHT with minimal energy consumption.
