Traffic Minimizing Caching and Latent Variable Distributions of Order Statistics
Joonas Pääkkönen, Prathapasinghe Dharmawansa, Ragnar Freij-Hollanti +2
Given a statistical model for the request frequencies and sizes of data objects in a caching system, we derive the probability density of the size of the file that accounts for the…
Coded Caching Clusters with Device-to-Device Communications
Joonas Pääkkönen, Amaro Barreal, Camilla Hollanti +1
We consider a geographically constrained caching community where popular data files are cached on mobile terminals and distributed through Device-to-Device (D2D) communications. Fu…
Coordination protocol for inter-operator spectrum sharing based on spectrum usage favors
Bikramjit Singh, Konstantinos Koufos, Olav Tirkkonen
Currently, mobile network operators are allocated spectrum bands on an exclusive basis. While this approach facilitates interference control, it may also result in low spectrum uti…
Coordination protocol for inter-operator spectrum sharing in co-primary 5G small cell networks
Bikramjit Singh, Sofonias Hailu, Konstantinos Koufos +4
We consider spectrum sharing between a limited set of operators having similar rights for accessing spectrum. A coordination protocol acting on the level of the Radio Access Networ…
Co-primary inter-operator spectrum sharing over a limited spectrum pool using repeated games
Bikramjit Singh, Konstantinos Koufos, Olav Tirkkonen +1
We consider two small cell operators deployed in the same geographical area, sharing spectrum resources from a common pool. A method is investigated to coordinate the utilization o…
Device-to-Device Data Storage with Regenerating Codes
Joonas Pääkkönen, Camilla Hollanti, Olav Tirkkonen
Caching data files directly on mobile user devices combined with device-to-device (D2D) communications has recently been suggested to improve the capacity of wireless net6works. We…
