Abstract:The hardware and low-level software in many mobile de-
vices are capable of mobile-to-mobile communication, in-
cluding ad-hoc mode for 802.11, Bluetooth, and cognitive
We have started to leverage this capability to provide in-
terpersonal communication both over infrastructure networks
(the Internet), and over ad-hoc and delay-tolerant networks
composed of the mobile devices themselves.
This network is fully decentralized so it can function with-
out any infrastructure, but takes advantage of Internet con-
nections when available. Devices may communicate when-
ever they are able to exchange packets. All interpersonal
communication is encrypted and authenticated so packets
may be carried by devices belonging to untrusted others.
One challenge in a fully decentralized network is rout-
ing. Our design uses Rendezvous Points (RPs) and Dis-
tributed Hash Tables (DHTs) for delivery over the Internet,
and hop-limited broadcast and Delay Tolerant Networking
(DTN) within the ad-hoc network.
Each device has a policy that determines how many pack-
ets may be forwarded, and a packet prioritization mecha-
nism that favors packets likely to consume fewer network
resources. A goal of this design and implementation is to
provide useful interpersonal communications using at most
1% of any given resource on mobile devices.
