In the multi-access edge computing (MEC) environment, app vendors’ data can be cached on edge servers to ensure low-latency data retrieval. Massive users can simultaneously access edge servers with high data rates through flexible allocations of transmit power. The ability to manage networking resources offers unique opportunities to app vendors but also raises unprecedented challenges. To ensure fast data retrieval for users in the MEC environment, edge data caching must take into account the allocations of data, users, and transmit power jointly. We make the first attempt to study the Data, User, and Power Allocation (DUPA ) problem, aiming to serve the most users and maximize their overall data rate. First, we formulate the DUPA problem and prove its -completeness. Then, we model the DUPA problem as a potential DUPA game admitting at least one Nash equilibrium and propose a two-phase …
