Caching decreases content access time by keeping contents closer to the clients. In this paper we show that network coding chunks of different contents and storing them in cache, can be beneficial. Recent research considers caching network coded chunks of same content, but not different contents. This paper proposes three different methods, IP, layered-IP and Greedy algorithm, with different performance...
We present an analytical framework to investigate the interplay between a communication graph and an overlay of social relationships. Particularly, we focus on geographical distance as the key element that interrelates the concept of routing in a communication network with interaction patterns on the social graph. Through this regime, we attempt to identify classes of social relationships that let...
We propose a model for network optimization in a non-cooperative game setting with specific reference to the Internet connectivity. We refer to the general model shown in internal report [1], where Autonomous Systems (AS) decisions on link creation and traffic routing are strategically based on realistic interconnection costs, keeping into account the peering/transit dichotomy. Equilibria existence...
