Abstract :
In this paper, we introduce a caching proxy architecture, which is used to (i) enable seamless device switching in the increasingly connected mobile user space, (ii) create user-based application optimizations, and (iii) realize energy savings in application contexts. We provide an overview of the static long-term gains that can be expected for individual applications using a generic cost approach and present numerical evaluations for the impact of different performance factors. We find that significant optimization potentials exist for cases of negligible computational overheads (i) downstream from the proxy if even small savings around 5% from the proxy downstream can be realized and (ii) upstream from the proxy if data needs to be replicated on the mobile user end in current multiple device scenarios.
