Exploiting Caching and Multicast for 5G Wireless Networks
TL;DR: It is shown that the multicast-aware caching problem is NP-hard and solutions with performance guarantees using randomized-rounding techniques are developed, showing that in the presence of massive demand for delay tolerant content, combining caching and multicast can indeed reduce energy costs.
Journal ArticleDOI
Distributed Cache Management in Information-Centric Networks
TL;DR: This paper presents an autonomic cache management approach for ICNs, where distributed managers residing in cache-enabled nodes decide on which information items to cache, and proposes four on-line intra-domain cache management algorithms with different level of autonomicity.
Proceedings ArticleDOI
Pursuing a Software Defined Information-centric Network
Dimitris Syrivelis,George Parisis,Dirk Trossen,Paris Flegkas,Vasilis Sourlas,Thanasis Korakis,Leandros Tassiulas +6 more
TL;DR: This paper outlines a possible realization in a novel design for ICN solutions and point to possible test bed deployments for future testing.
Proceedings ArticleDOI
On Uncoordinated Service Placement in Edge-Clouds
Onur Ascigil,Truong Khoa Phan,Argyrios G. Tasiopoulos,Vasilis Sourlas,Ioannis Psaras,George Pavlou +5 more
TL;DR: This paper proposes a set of practical, uncoordinated strategies for service placement in edge-clouds that can perform comparatively well with the optimal placement solution, which satisfies the maximum amount of user requests.
Proceedings ArticleDOI
Multicast-aware caching for small cell networks
TL;DR: In this paper, the authors proposed and analyzed a novel caching approach that can achieve significantly lower traffic compared to the traditional caching schemes, taking into account the fact that an operator can serve the requests for the same file that happen at nearby times via a single multicast transmission.
