Intelligent Reflecting Surfaces for Compute-and-Forward
Mahdi Jafari Siavoshani, Seyed Pooya Shariatpanahi, Naeimeh Omidvar
Compute-and-forward is a promising strategy to tackle interference and obtain high rates between the transmitting users in a wireless network. However, the quality of the wireless…
Multi-Message Private Information Retrieval with Private Side Information
Seyed Pooya Shariatpanahi, Mahdi Jafari Siavoshani, Mohammad Ali Maddah-Ali
We consider the problem of private information retrieval (PIR) where a single user with private side information aims to retrieve multiple files from a library stored (uncoded) at…
Coded Load Balancing in Cache Networks
Mahdi Jafari Siavoshani, Farzad Parvaresh, Ali Pourmiri +1
We consider load balancing problem in a cache network consisting of storage-enabled servers forming a distributed content delivery scenario. Previously proposed load balancing solu…
Storage, Communication, and Load Balancing Trade-off in Distributed Cache Networks
Mahdi Jafari Siavoshani, Ali Pourmiri, Seyed Pooya Shariatpanahi
We consider load balancing in a network of caching servers delivering contents to end users. Randomized load balancing via the so-called power of two choices is a well-known approa…
Linear Index Coding via Graph Homomorphism
Javad B. Ebrahimi, Mahdi Jafari Siavoshani
It is known that the minimum broadcast rate of a linear index code over is equal to the of the underlying digraph. In [3] it is proved that for $\mathbb{…
On Index Coding and Graph Homomorphism
Javad B. Ebrahimi, Mahdi Jafari Siavoshani
In this work, we study the problem of index coding from graph homomorphism perspective. We show that the minimum broadcast rate of an index coding problem for different variations…
On AVCs with Quadratic Constraints
Farzin Haddadpour, Mahdi Jafari Siavoshani, Mayank Bakshi +1
In this work we study an Arbitrarily Varying Channel (AVC) with quadratic power constraints on the transmitter and a so-called "oblivious" jammer (along with additional AWGN) under…
Multi-terminal Secrecy in a Linear Non-coherent Packetized Networks
Mahdi Jafari Siavoshani, Christina Fragouli
We consider a group of m+1 trusted nodes that aim to create a shared secret key K over a network in the presence of a passive eavesdropper, Eve. We assume a linear non-coherent net…
Subspace Properties of Network Coding and their Applications
Mahdi Jafari Siavoshani, Christina Fragouli, Suhas Diggavi
Systems that employ network coding for content distribution convey to the receivers linear combinations of the source packets. If we assume randomized network coding, during this p…
On the Capacity of Non-Coherent Network Coding
Mahdi Jafari Siavoshani, Soheil Mohajer, Christina Fragouli +1
We consider the problem of multicasting information from a source to a set of receivers over a network where intermediate network nodes perform randomized network coding operations…
