Kravets National Technical University "Kharkiv Polytechnic Institute" ENERGY-EFFICIENT ROUTING AND MULTILEVEL CLUSTERING IN DYNAMIC DRONE NETWORKS Abstract . The article addresses the problem of improving the energy efficiency of swarm-based drone telecommunication systems operating in a MESH topology under conditions of limited energy resources and dynamically changing network structure. A multi-level cluster model for organizing a swarm MESH drone network is proposed, based on a hierarchical distribution of roles among nodes and multi-level traffic aggregation. It is shown that the implementation of such a model ensures a more uniform distribution of energy load and extends the network lifetime by approximately 15% over a wide range of load coefficients. Keywords : clustering, energy saving, swarm drones, MESH network, network lifetime.
