Abstract:
This document is written in the context of the Delay Tolerant
Networking Research Group and will be presented for reviewing by that
group. This document defines dLife, an opportunistic routing protocol
that takes advantage of time-evolving social structures. dLife
belongs to the family of social-aware opportunistic routing protocols
for intermittently connected networks. dLife operates based on a
representation of the dynamics of social structures as a weighted
contact graph, where the weights (i.e., social strengths) express how
long a pair of nodes is in contact over different period of times. It
considers two complementary utility functions: Time-Evolving Contact
Duration (TECD) that captures the evolution of social interaction
among pairs of users in the same daily period of time, over
consecutive days; and TECD Importance (TECDi) that captures the
evolution of user's importance, based on its node degree and the
social strength towards its neighbors, in different periods of time.
It is intended for use in wireless networks where there is no
guarantee that a fully connected path between any source -
destination pair exists at any time, a scenario where traditional
routing protocols are unable to deliver bundles. Such networks can be
sparse mesh, in which case intermittent connectivity is due to lack
of physical connections, or dense mesh, in which case intermittent
connectivity may be due to high interference or shadowing. In any
case, intermittent connectivity can also be due to the availability
of devices (e.g., unavailable due to power saving rules). The
document presents an architectural overview followed by the protocol
specification.
