A relative time implementation for delay-tolerant networks

This demo shows a relative time implementation for the delay-tolerant networking architecture. In this system, bundle age is used to track expiration in situations where ac curate real world time is not available. The relative time functionality is implemented on top of the DTN2 reference implementation and the Bytewalla Android implementation which allows for its use on commercial mobile devices. Our demo, using multiple smartphones and netbooks, shows that devices are still able to communicate despite unsynchronized or incorrect clocks.
