SUMMARY:DROiD: Adapting to Individual Mobility Pays Off in Mobile Data
 Offloading
DESCRIPTION:Cellular operators count on the potentials of offloading
 techniques to relieve their overloaded data channels. Beyond standard
 access point-based offloading strategies\, a promising alternative is to
 exploit opportunistic direct communication links between mobile devices.
 Nevertheless\, achieving efficient device-to-device offloading is
 challenging\, as communication opportunities are\, by nature\, dependent on
 individual mobility patterns. We propose\, design\, and evaluate DROiD
 (Derivative Re-injection to Offload Data)\, an original method to finely
 control the distribution of popular contents throughout a mobile network.
 The idea is to use the infrastructure resources as seldom as possible. To
 this end\, DROiD injects copies through the infrastructure only when
 needed: (i) at the beginning\, in order to trigger the dissemination\, (ii)
 if the evolution of the opportunistic dissemination is below some expected
 pace\, and (iii) when the delivery delay is about to expire\, in order to
 guarantee 100% diffusion. Our strategy is particularly effective in highly
 dynamic scenarios\, where sudden creation and dissolution of clusters of
 mobile nodes prevent contents to diffuse properly. We assess the
 performance of DROiD by simulating a traffic information service on a
 realistic large-scale vehicular dataset composed of more than 10\,000
 nodes.DROiD substantially outperforms other offloading strategies\, saving
 more than 50% of the infrastructure traffic even in the case of tight
 delivery delay constraints. DROiD allows terminal-to-terminal offloading of
 data with very short maximum reception delay\, in the order of minutes\,
 which is a realistic bound for cellular user acceptance.
