Unmanned Aeronautical Ad-hoc Networks: Enhancing the Reactive-Greedy-Reactive Protocol and Introducing a New Mobility Model
Jean-Daniel Medjo Me Biomo · 2014
Unmanned Aeronautical Ad-hoc Networks (UAANETs) are infrastructure-less and selforganizing networks that are formed by small and medium sized Unmanned Aerial Vehicles (UAVs) that are deployed for a wide range of civilian and military applications.Having a reliable routing protocol for communication between the UAVs is critical.Our goal in this research is twofold.First, we enhance one of the existing routing protocols, the Reactive-Greedy-Reactive (RGR) protocol.In doing so, we propose the Optimized-RGR.Secondly, we propose the Enhanced Gauss-Markov (EGM) mobility model for UAANET simulations to replace the widely used, but unrealistic, Random Waypoint (RWP) mobility model.Simulations performed using the OPNET simulator show that Optimized-RGR outperforms RGR.There is a 5.3% increase in Packet Delivery Ratio at a negligible cost in latency.Furthermore, realistic mobility models, including EGM, show a lot of network partitioning.Therefore, this should be taken very seriously when developing a routing protocol for UAANETs.
