Robust content dissemination in disrupted environments

Abstract

Content dissemination in disrupted networks poses a big challenge, given that the current routing architectures of ad hoc networks require establishing routes from sources to destinations before content can disseminated between them. In ad hoc networks subject to disruption, lack of reliable connectivity between producers and consumers of information makes most routing protocols perform very poorly or not work at all. We present DIRECT (DIsruption REsilient Content Transport), which is a content dissemination approach for ad hoc networks that exploits in-network storage and the hop-by-hop dissemination of named information objects. Simulation experiments illustrate that DIRECT provides a high degree of reliability while maintaining low levels of delivery latencies and signaling and data overhead compared to traditional on-demand routing and epidemic routing.
