Abstract
Content-Centric Networking (CCN) focuses on content acquisition rather than end-to-end communication by decoupling content resources from special hosts. CCN does not need maintain stable paths between nodes and is independent of IP addresses, which make CCN convenient and efficient for mobile ad hoc network (MANET). In this paper, we develop an analytical model of content acquisition for Content-Centric MANET (CCM) in two-dimensional case, which considers in-network caching and nodes mobility. Closed-form expressions for round trip time and throughput are derived as functions of miss probabilities. From the expressions, we can obtain the relationship among the round trip time, cache size and content popularity. Simulations show that our model can be used as a guide to design CCM and to evaluate its performance.
