IBR-DTN is a free Android-based bundle protocol daemon developed by IBR TU Braunschweig. It is designed to provide an API for DTN (Delay-Tolerant Networking) applications to exchange and route bundles between them based on RFC5050.

The program offers a reliable and efficient way to transmit data in environments where traditional networking is not possible due to network disruptions, low bandwidth, or high latency. IBR-DTN is easy to install and configure and provides a user-friendly interface that makes it accessible to both novice and advanced users.

With IBR-DTN, users can exchange and route bundles with other DTN applications running on the same or different devices. The program ensures that data is delivered even in challenging network conditions, making it an ideal solution for users who require a reliable network connection.
