In this paper, the selfish caching problem in multi-hop cellular networks (MCNs) is formulated as a non-cooperative game: data caching game. Towards balancing the tradeoffs between data availability and query delay in MCNs, an incentive mechanism based upon a payment model is set up for data caching game. The data caching game is proved to be a potential game. Thus, for the game, pure Nash equilibra can be obtained and the best response dynamics converge to a pure Nash equilibrium. Moreover, by properly setting the payoff distribution rule, caching proxies have incentive to or not to cache the same data to some extent. Thereby, the performance of data availability and query delay can be tuned in an adjustable-way, which results in a desirable service performance that service provider intends to achieve.
