Hierarchical link-state routing in disruption-tolerant networks

Disruption-Tolerant Networking (DTN) is the technological tool for operating in networks that while performant are intermittently available and may lack end-to-end connectivity. Routing in DTN networks is an open research problem and there has been interest in tying DTN resiliency to Mobile Ad-hoc Networks (MANET) performance. Using the Multi Interface Communications Software (MICS) framework, we explore use of a linkstate routing protocol in DTN environment. We detail the improvements done to the routing protocol to enhance operation in hierarchical network topologies.
