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.
