Policy-based routing for Flying Adhoc Networks

Strategic and profile-based communication in wireless adhoc networks is complex since it is important to distinguish between different traffic types and their routes to ensure the required performance over a dynamic network. In order to face this challenge, we developed a new concept of a policy-based routing protocol for flying adhoc networks, having the Babel routing protocol as a starting point. Policies are identified based on the Type-of-Service field, allowing the augmented Babel protocol to select routes based on the properties of different types of traffic. Our approach differentiates route costs per traffic profile to consider different requirements in the route selection process.The evaluation shows that applying our approach improves traffic-specific performance; namely, tail-latency in video traffic can be significantly improved by one order of magnitude.
