This document is a product of the Delay Tolerant Networking Research
Group and has been reviewed by that group.  No objections to its
publication as an RFC were raised.

This document defines PRoPHET, a Probabilistic Routing Protocol using
History of Encounters and Transitivity.  PRoPHET is a variant of the
epidemic routing protocol for intermittently connected networks that
operates by pruning the epidemic distribution tree to minimize
resource usage while still attempting to achieve the %best-case
routing capabilities of epidemic routing.  It is intended for use in
sparse mesh networks where there is no guarantee that a fully
connected path between the source and destination exists at any time,
rendering traditional routing protocols unable to deliver messages
between hosts.  These networks are examples of networks where there
is a disparity between the latency requirements of applications and
the capabilities of the underlying network (networks often referred
to as delay and disruption tolerant).  The document presents an
architectural overview followed by the protocol specification.
