Information Centric Fog Network for Incentivized Collaborative Caching in Internet of Everything

Résumé

Current mobile network infrastructure has a hard time keeping up with the constant content demand by an increasing number of smart devices, both in terms of bandwidth and cost. At the same time, the advent of devices with relatively high resources (computing, communications, caching) allows to offload computation, control, cache and communication near the users as in Edge or Fog Networking. If we consider the caching resource, the basic challenges are: (i) How and who can form fogs for local content caching? and (ii) How to interact with the fog for efficient content caching and retrieval? To address these, we leverage Information Centric Networking (ICN) to propose IS-Fog, a social-aware fog network where the content is the first class citizen. We first classify a device's eligibility to provide content using a novel content-based centrality. At the same time, we incentivize users to self-organize and share their device's resources and cache in the fog. We then propose a social-aware content caching and a distribution scheme to model fog interactions allowing nodes to collaboratively cache content locally. We evaluate IS-Fog using realistic mobility traces of 2,986 nodes. Results shows that IS-Fog is a scalable and efficient content caching and distribution approach compared to existing schemes.
