Replication Routing in DTNs: A Resource Allocation Approach

Enpassant: Anonymous Routing for Dtns

Disruption-Tolerant Networking holds a great deal of potential for making communications easier and more flexible in pervasive assistive environments. However, security and privacy must be addressed to make these communications acceptable with respect to protecting patient privacy. We propose EnPassant, a system for using disruption-tolerant networking in privacy-preserving way. EnPassant uses ...

MobySpace : Mobility Pattern Space Routing for DTNs

Simulation parameters: 50 mobile nodes, 25 locations, pause time at each location is uniformly distributed on [5s,15s], nodes generate bundles every 30s toward each of the others during the first 500s, simulation time is 4000s. This work has been funded by the ANRT through a CIFRE grant, and by EuronetLab, and was conducted at the Université Pierre et Marie Curie (1) and Thales Communications (...

Psychic Routing: Upper Bounds on Routing in Private DTNs

We present early work investigating a one-way delay-tolerant communications channel which affords its users perfect unobservability at the price of a limited bitrate. We suggest an unrealizable protocol, Psychic Routing, against which we can compare the performance of concrete DelayTolerant Networking routing schemes. We then use Psychic Routing to evaluate the performance of routing in our per...

RAPID : Resource Allocation Routing for DTN Paradigm

Impact of source counter on routing performance in resource constrained DTNs

We study routing schemes for Disruption Tolerant Networks (DTNs) where transmission bandwidth is scarce resource. In such a setting, a key issue is how to schedule the transmission of packets under limited bandwidth to optimize performance. Such a scheduling consists of source control (i.e., source nodes choosing a routing scheme) and the local transmission scheduling performed by each node. Ex...
