Özet
Unmanned Aerial Vehicular (UAV) networks extend wireless access for devices without infrastructure coverage, and also help establish a connectivity backbone during military reconnaissance and disaster events. This paper focuses on the design of a resilient end-to-end connectivity paradigm under unique architectural and scenario assumptions. First, the UAVs themselves are equipped with multiple interfaces that use standardized protocols, with associated variation in data throughout, range, and bit error rates. Second, there may be adversarial agents seeking to disrupt connectivity through targeted jamming in 3D spaces. Third, we assume an overlay software defined control plane, where the UAVs function as software switches, able to execute forwarding commands and determine preferred routes under controller directives. Our proposed approach devises metrics that influence the choice of the wireless interface and weights edges formed between UAV pairs. Further, it also uses a multi-layer graph model and creates maximally separated paths in 3D space to ensure resiliency to jamming. Simulation results conducted for urban scenarios reveal 34% improvement in enhanced resiliency for end-to-end outages by trading off 12% increase in latency over competing approaches.

Here, we analyze how average e2e delays of the determined routes change based on the number of UAVs in the network. Nine different topologies are created, of sizes varying from 20 UAVs to 180 UAVs . Topologies consisting of increasing number of UAVs are composed as super-sets of the previous ones. As seen in Fig. 4c, the best performance is achieved by the traditional shortest path algorithm, since it only focuses on calculating optimal paths in terms of e2e delay. Moreover, the calculated routes with the use of our heuristic performs slightly worse in terms of delay contributed by lines (13-14) in Algorithm 1. In these lines, weights of adjacent links to the shortest path are multiplied to avoid their selection in the path, thereby trading off latency with the goal of improving resiliency. V. CONCLUSION In this paper, we proposed a novel routing framework for SD-UAV networks that determines multiple disjoint routes for a given source-destination pair in order to improve resiliency of the network. To this end, our proposed resiliency metric combined with the heuristic method reduced the outage rate of end-to-end connections in the presence of interferers. Finally, we showed that the proposed framework performs better in terms of end-to-end outage with slight degradation in end-to-end delay, when compared to traditional algorithms.
