Abstract

This paper presents an evaluation of in-network caching strategies for efficient delivery of content to mobile devices that are intermittently connected to the network. Placement of content into in-network caches is formulated as an optimization problem that minimizes access latency under certain cost constraints. Several heuristic solutions (longest lifetime, split & longest lifetime and proportional probability to lifetime) are investigated via numerical examples and simulations. The results show that the proposed methods offer significant performance improvement over random caching and can approach the performance of exhaustive caching at every node with reduced storage cost.
