Online Edge Caching and Wireless Delivery in Fog-Aided Networks with Dynamic Content Popularity
Seyyed Mohammadreza Azimi, Osvaldo Simeone, Avik Sengupta +1
Fog Radio Access Network (F-RAN) architectures can leverage both cloud processing and edge caching for content delivery to the users. To this end, F-RAN utilizes caches at the edge…
Online Edge Caching in Fog-Aided Wireless Network
Seyyed Mohammadreza Azimi, Osvaldo Simeone, Avik Sengupta +1
In a Fog Radio Access Network (F-RAN) architecture, edge nodes (ENs), such as base stations, are equipped with limited-capacity caches, as well as with fronthaul links that can sup…
Improved Approximation of Storage-Rate Tradeoff for Caching with Multiple Demands
Avik Sengupta, Ravi Tandon
Caching at the network edge has emerged as a viable solution for alleviating the severe capacity crunch in modern content centric wireless networks by leveraging network load-balan…
Fog-Aided Wireless Networks for Content Delivery: Fundamental Latency Trade-Offs
Avik Sengupta, Ravi Tandon, Osvaldo Simeone
A fog-aided wireless network architecture is studied in which edge-nodes (ENs), such as base stations, are connected to a cloud processor via dedicated fronthaul links, while also…
Cache Aided Wireless Networks: Tradeoffs between Storage and Latency
Avik Sengupta, Ravi Tandon, Osvaldo Simeone
We investigate the fundamental information theoretic limits of cache-aided wireless networks, in which edge nodes (or transmitters) are endowed with caches that can store popular c…
Fundamental Limits of Caching with Secure Delivery
Avik Sengupta, Ravi Tandon, T. Charles Clancy
Caching is emerging as a vital tool for alleviating the severe capacity crunch in modern content-centric wireless networks. The main idea behind caching is to store parts of popula…
