Center node: "a coalition based communication framework for intelligent flying ad hoc networks"
  Abstract: In this paper, we develop the intelligent networking framework for Flying Ad-hoc Networks (FANETs), where a coalition-based model is designed. Firstly, we present a brief survey to show the state-of-the art studies on the intra-communication of unmanned aerial vehicle (UAV) swarms. The features and deficiencies of existing models are analyzed. To capture the task-driven requirement of the flying multi-agent system, a coalition-based framework is proposed. We discuss the composition, networking mode and the classification of data transmission. After that, the application scenario of UAV coalitions is given, where large-scale, distributed and highly dynamic characteristics greatly increase the difficulty of resource optimization for UAVs. To tackle the problem, we design an artificial intelligence-based optimization architecture, which mainly includes the game model, machine learning and the real-time decision. Under the guidance of game theories and machine learning, UAVs can make comprehensive decisions by combining the previous training results with their own sensing, information interaction and game strategies. Finally, a preliminary case and promising open issues of UAV coalitions are studied.
