Mobility-Aware Caching in D2D Networks

  title={Mobility-Aware Caching in D2D Networks},
  author={Rui Wang and Jun Zhang and Shenghui Song and Khaled Ben Letaief},
  journal={IEEE Transactions on Wireless Communications},
Caching at mobile devices can facilitate device-to-device (D2D) communications, which may significantly improve spectrum efficiency and alleviate the heavy burden on backhaul links. However, most previous works ignored user mobility, thus having limited practical applications. In this paper, we take advantage of the user mobility pattern by the inter-contact times between different users, and propose a mobility-aware caching placement strategy to maximize the data offloading ratio, which is… CONTINUE READING
