recommendations! Published in 2025 at "IEEE Internet of Things Journal"

DOI: 10.1109/jiot.2024.3478255

Abstract: Coded caching has emerged as a promising technique to alleviate traffic congestion by strategically creating coded multicasting opportunities, even for caches with different demands. For a two-layer cache-aided hierarchical network consisting of a central server,… read more here.

recommendations! Published in 2021 at "IEEE Transactions on Communications"

DOI: 10.1109/tcomm.2020.3045787

Abstract: Cache-aided wireless device-to-device (D2D) networks have demonstrated more promising performance improvement for video distribution than conventional distribution methods; thus, understanding the fundamental scaling behavior of such networks is highly important. However, the existing scaling laws… read more here.

DOI: 10.1109/tcomm.2024.3450595

Abstract: We study timeliness in cache-aided networks where the inter-update times on the links are not necessarily exponentially distributed. We focus on the set of non-arithmetic distributions for inter-update times, which includes continuous probability distributions as… read more here.

DOI: 10.1109/tit.2022.3157835

Abstract: Coded caching is a promising technique to smooth out network traffic by storing part of the library content at the users’ local caches. The seminal work on coded caching for single file retrieval by Maddah-Ali… read more here.

DOI: 10.1109/tvt.2021.3136083

Abstract: In this paper, we consider an underlay cognitive hybridsatellite-terrestrial network (CHSTN) which constitutes a primary satellite source communicating with its multiple terrestrial primary receivers and two non-orthogonal multiple access (NOMA) secondary terrestrial users exchanging their… read more here.

DOI: 10.1109/twc.2021.3112958

Abstract: Coded multicasting is considered to be an effective approach to simultaneously serve multiple users in the same frequency/time/code resource, which is made possible by exploiting the information available in users’ caches. Recently, non-orthogonal multiple access… read more here.
