Robust content dissemination in disrupted environments


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
