Abstract

We present procedures that exploit mobility prediction and prefetching to enhance offoading of trafic from mobile networks to WiFi hotspots, for both delay tolerant and delay sensitive trafic. We evaluate the procedures in terms of the percentage of offoaded trafic, the data transfer delay, and the cache size used for prefetching. The evaluation considers empirical measurements and shows how various parameters infuence the performance of the procedures, and their robustness to time and throughput estimation errors.
