The proliferation of mobile devices boosts mass multimedia content delivery in wireless environments. Wireless content delivery network systems strongly require a lightweight caching strategy because of the processing capability constraints. In this paper, we introduce a one-touch caching scheme that exploits a temporal locality property as the minimum intelligence by making cache servers blindly cache the most recently requested content. Simulation results show that our strategy with little overhead has a comparable performance to conventional schemes such as LRU (least recently used), LFU (least frequently used) and other variants with heavy computational overheads.
