Model and Evaluation of Content Retrieval Through Virtual Networking Functions in Edge Computer Architecture in Mobile Networks
Abstract
The increase in mobile traffic consumption by users grows every year. Demanding resources for mobile device applications such as processing power and storage capacity has led the architecture of mobile networks to redesign into a centralized structure, C-RANs. The centralized nature of C-RAN makes it possible to manage resources more efficiently through virtualization techniques and opens the horizon for ubiquitous computing to process IoT paradigm data. On the other hand, providing computational resources close to base stations, as suggested by the Mobile Edge Computing architecture, allows delay-sensitive applications to be more user-friendly. In this paper, a mixed integer linear programming problem is formulated for the positioning of caches as virtual network functions and the location of content retrieval by users. The problem is to minimize the cost of recovery for users, as well as minimize the deployment of virtual functions.
