SUMMARY:Caching Games between Content Providers and Internet Service
 Providers
DESCRIPTION:We consider a scenario where an Internet Service Provider (ISP)
 serves users that choose digital content among M Content Providers (CP). In
 the status quo\, these users pay both access fees to the ISP and content
 fees to each chosen CP\; however\, neither the ISP nor the CPs share their
 profit. We revisit this model by introducing a different business model
 where the ISP and the CP may have motivation to collaborate in the
 framework of caching. The key idea is that the ISP deploys a cache for a CP
 provided that they share both the deployment cost and the additional profit
 that arises due to caching. Under the prism of coalitional games\, our
 contributions include the application of the Shapley value for a fair
 splitting of the profit\, the stability analysis of the coalition and the
 derivation of closed-form formulas for the optimal caching policy.Our model
 captures not only the case of non-overlapping contents among the CPs\, but
 also the more challenging case of overlapping contents\; for the latter
 case\, a non-cooperative game among the CPs is introduced and analyzed to
 capture the negative externality on the demand of a particular CP when
 caches for other CPs are deployed.\n\nJoint work with S. Elayoubi\, E.
 Altman\, and Y. Hayel to be presented at the 10th EAI International
 Conference on Performance Evaluation Methodologies and Tools (Valuetools
 2016). The full version of the paper has been selected to be published in a
 special issue of the Elsevier journal of Performance Evaluation (PEVA).
