D2D Coded Caching from Two Classes of Optimal DPDAs using Cross Resolvable Designs
Rashid Ummer N. T., B. Sundar Rajan
Device to device (D2D) communication is one of the most promising techniques for fifth-generation and beyond wireless communication systems. This paper considers coded caching in a…
Single-Server Pliable Private Information Retrieval with Identifiable Side Information
Megha Rayer, Charul Rajput, B. Sundar Rajan
In Pliable Private Information Retrieval (PPIR) with a single server, messages are partitioned into non-overlapping classes. The user wants to retrieve a message from its desir…
A New Hotplug Coded Caching Scheme Using PDAs
Mallikharjuna Chinnapadamala, Charul Rajput, B. Sundar Rajan
In the original coded caching model introduced by Maddah-Ali and Niesen in 2014, the server starts broadcasting only after it receives demands from all the users. So, all the users…
Optimal Placement Delivery Arrays from -Designs with Application to Hierarchical Coded Caching
Rashid Ummer N. T., B. Sundar Rajan
Coded caching scheme originally proposed by Maddah-Ali and Niesen (MN) achieves an optimal transmission rate under uncoded placement but requires a subpacketization level w…
Multi-access Distributed Computing Models from Map-Reduce Arrays
Shanuja Sasi, Onur Günlü, B. Sundar Rajan
A novel distributed computing model called "Multi-access Distributed Computing (MADC)" was recently introduced in http://www.arXiv:2206.12851. In this paper, we represent MADC mode…
