Abstract/Description:
We study the throughput and delay characteristics of wireless networks based on the Named Data Networking architecture, where users are mainly interested in retrieving content stored in the network, rather than in maintaining source-destination communication. Nodes are assumed to be uniformly distributed in the network area. Each node has a limited-capacity Content Store, which it uses to cache contents according to the proposed caching scheme. We consider a content-centric traffic model with a general content popularity distribution, where users use multihop communication to retrieve the requested content from the closest cache.

Our study begins with precisely establishing the definitions of throughput and delay suitable for content-centric networks. Then, we derive the throughput-delay tradeoff of the proposed network paradigm for a general content popularity distribution, and formulate the problem of joint optimization of caching and forwarding strategies. We, then, evaluate the network performance for a Zipf content popularity distribution, letting the number of content types and the network size both go to infinity. In addition, we extend our analysis in various directions, considering contents with different sizes and hybrid network scenarios. Finally, through extensive simulations, we verify our theoretical results.
