Optimal caching problem
WebIn this paper, we formulate the Profit-Maximizing Edge Data Caching (PMEDC) as a constrained optimization problem. For PMEDC in small scale scenarios, we propose an optimization model named PMEDC-IP that can derive the optimal caching strategy. For PMEDC in large scale scenarios, we propose an approximation algorithm named MPF … WebDec 17, 2024 · In this paper, we study data caching problem in edge computing in order to minimize the system cost, including data caching cost, data transmission cost and data purchase cost. The traditional data center is only the choice to purchase data, the data is always available after purchasing.
