Dynamic Wireless Caching Solution for Cellular Networks

Description :

Wireless caching in cellular networks is a hot research topic. Different types of networks, such as macro-cellular, heterogeneous, D2D, C-RAN and F-RAN, have applied caching techniques and solutions. The main focus has been on how to place and deliver contents efficiently; i.e. what to cache and how to serve users. Some solutions have also considered coded caching, which combines content placement and transmission code design. Coded caching was first proposed for a shared link caching network with one transmitter and K users. However, many practical challenges remain for implementing coded caching in realistic scenarios. This PhD research proposal aims to address these challenges by considering dynamic scenarios with respect to file popularity and number of users, joint coded caching and MIMO design, and channel imperfection and error correction. These are realistic assumptions that can help in applying coded caching in practice. The goal is to achieve higher performance gains than existing solutions.
