This paper proposes Advanced Fast Recovery OLSR (AFR-OLSR) for Unmanned Aerial Vehicles (UAVs) with sudden link outages, and implements a multipath version of this protocol. AFR-OLSR can maintain high packet delivery ratio and hardly bring extra network delay in the scenario of nodes suddenly offline or moving at high speed in UAV swarm. We improve the route calculation rule by defining a new link state and using penalty function to reduce the priority of selecting the link state. We use a constant bit rate (CBR) application running on selected nodes to simulate traffic in the network and measure the performance of data transmission. Experimental results show that the proposed protocol has a significant performance improvement.
