Combination Networks with or without Secrecy Constraints: The Impact of Caching Relays.
IEEE Journal on Selected Areas in Communications(2018)
摘要
This paper considers a two-hop network architecture known as a combination network, where a layer of relay nodes connects a server to a set of end users. In particular, a new model is investigated, where the intermediate relays employ caches in addition to the end users. First, a new centralized coded caching scheme is developed that utilizes maximum distance separable coding, jointly optimizes ca...
