Dynamic Source Routing

The Dynamic Source Routing (DSR) protocol has been speficied by the IETF in RFC 4728 in 2007 but the protocol is much older. Among the other MANET routing protocols, DSR has particular properties that makes it a good candidate to implement a multi-path routing approach. In contrast to unicast routing, where each node only stores a single route for each destination, multiple routes are discovered and kept as backup when the primary route breakes or for load balancing.

Based on the DES-SERT routing framework, 11 variants of DSR have been implemented and evaluated in the DES-Testbed. Nevertheless, the work is not finished. We need different experiment scenarios and a better understanding of the influences of particular parameters on the outcome.

Objectives

• Get familar with the DSR variants and the DES-SERT routing framework
• Re-run an older experiment series in the much larger testbed
• Optimize the throughput, redundancy, delay, and packet-reordering by running further experiments
• Propose and implement extensions to the DSR variants and/or implement further multi-path variants
• Evaluate the results
