Title: | Base Station-Assisted Cooperative Network Coding for Cellular Systems With Link Constraints | Authors: | Arslan, Suayb S. Pourmandi, Massoud Haytaoglu, Elif |
Publisher: | Ieee | Series/Report no.: | IEEE International Symposium on Information Theory | Abstract: | We consider a novel distributed data storage/caching scenario in a cellular network, where multiple nodes may fail/depart simultaneously To meet reliability, we allow cooperative regeneration of lost nodes with the help of base stations allocated in a set of hierarchical layers1. Due to this layered structure, a symbol download from each base station has a different cost, while the link capacities between the nodes of the cellular system and the base stations are also constrained. Under such a setting, we formulate the fundamental trade-off with closed form expressions between repair bandwidth cost and the storage space per node. Particularly, the minimum storage as well as bandwidth cost points are formulated. Finally, we provide an explicit optimal code construction for the minimum storage regeneration point for a special set of system parameters. | URI: | https://doi.org/10.1109/ISIT50566.2022.9834669 | ISBN: | 9781665421607 9781665421591 |
