Criticality of Large Delay Tolerant Networks Via Directed Continuum Percolation in Space-Time

Free registration required

Executive Summary

Delay-Tolerant Networking (DTN) is a last-resort networking paradigm for mobile nodes when direct and multi-hop connections are infeasible, i.e., the network is not connected and nodes have to carry the messages to the next node (store-carry-forward). The authors study the capacity of DTN to deliver a message to its destination(s) in the framework of the percolation theory. They are interested in finding the circumstances under which the lifetime of a message becomes infinite (with some positive probability) so that the message could reach a recipient located at an arbitrary distance from the source.
