Coded Caching for Heterogeneous Wireless Networks
Jad Hachem, Nikhil Karamchandani, Suhas Diggavi +1
This chapter provides an overview of coded caching in the context of heterogeneous wireless networks. We begin by briefly describing the key idea behind coded caching and then disc…
Energy-Efficiency Gains of Caching for Interference Channels
Jad Hachem, Urs Niesen, Suhas Diggavi
This paper initiates the study of energy-efficiency gains provided by caching. We focus on the cache-aided Gaussian interference channel in the low-SNR regime. We propose a strateg…
Caching with Partial Adaptive Matching
Jad Hachem, Nikhil Karamchandani, Sharayu Moharir +1
We study the caching problem when we are allowed to match each user to one of a subset of caches after its request is revealed. We focus on non-uniformly popular content, specifica…
Degrees of Freedom of Cache-Aided Wireless Interference Networks
Jad Hachem, Urs Niesen, Suhas Diggavi
We study the role of caches in wireless interference networks. We focus on content caching and delivery across a Gaussian interference network, where both transmitters and receiver…
A Layered Caching Architecture for the Interference Channel
Jad Hachem, Urs Niesen, Suhas Diggavi
Recent work has studied the benefits of caching in the interference channel, particularly by placing caches at the transmitters. In this paper, we study the two-user Gaussian inter…
Effect of Number of Users in Multi-level Coded Caching
Jad Hachem, Nikhil Karamchandani, Suhas Diggavi
It has been recently established that joint design of content delivery and storage (coded caching) can significantly improve performance over conventional caching. This has also be…
Coded Caching for Multi-level Popularity and Access
Jad Hachem, Nikhil Karamchandani, Suhas Diggavi
To address the exponentially rising demand for wireless content, use of caching is emerging as a potential solution. It has been recently established that joint design of content d…
Content Caching and Delivery over Heterogeneous Wireless Networks
Jad Hachem, Nikhil Karamchandani, Suhas Diggavi
Emerging heterogeneous wireless architectures consist of a dense deployment of local-coverage wireless access points (APs) with high data rates, along with sparsely-distributed, la…
Coding with Encoding Uncertainty
Jad Hachem, I-Hsiang Wang, Christina Fragouli +1
We study the channel coding problem when errors and uncertainty occur in the encoding process. For simplicity we assume the channel between the encoder and the decoder is perfect.…
