An approach to ensuring availability of wireless mesh networks for crisis management is proposed. The approach comprises, first, means for automatic scanning of the network nodes and formation of its graph model, second, algorithms for analyzing the dynamically changing graph network and, third, decision-making tool for automated spatial movement of drones equipped with additional router nodes to places of real and potential network availability violations to eliminate these violations. A hardware-software prototype of the availability ensuring components has been developed. The constructed solutions, including their subjection to energy resource exhaustion attacks have been analyzed.
