| Abstract |
UAV networks have been in the spotlight of the research community on the last decade. One of the civil applications in which UAV networks may have more potential is in emergency response operations. Having a UAV network that is able to deploy autonomously and provide communication services in a disaster scenario would be very helpful for both victims and first responders. However, generating exploratory trajectories for these networks is one of the main issues when dealing with complex scenarios. We propose an algorithm based on the well-known Particle Swarm Optimization algorithm, in which the UAV team follows the networking approach known as Delay Tolerant Network. We pursue two main goals, the first is exploring a disaster scenario area, and the second is making the UAVs converge to several victims groups discovered during the exploration phase. We have run extensive simulations for performing a characterization of the proposed algorithm. Both goals of the mission are successfully achieved with the proposed algorithm. Besides, in comparison to an optimal trajectory planning algorithm that sweeps the entire disaster scenario, our algorithm is able to discover faster the 25%, 50% and 75% of the scenario victims and it converges faster. In addition, in terms of connections events between a victim and a UAV, our algorithm shows more frequent connections and less time between consecutive connections. (C) 2018 Elsevier B.V.
