Data Link Of MAV Swarm Autonomous Management System

Air-air data link adopt the wireless network protocol-ZigBee protocol which based on the international standard IEEE 802.15.4, to achieve UAV swarm organizing network communication in laboratory. This protocol includes high-level application layer, application convergence layer, network layer, MAC layer, physical layer. This paper studies data link related technologies of MAV swarm autonomous management system. This paper also introduces the key technology which used in the system, such as a distributed address allocation mechanism, slot allocation, CSMA-CA, O-QPSK and so on.This paper designed air-air data link for autonomous management system of MAV swarm, which is the integrated communication system of MAV swarm transfer and exchange information. This design of air-air data link using the tree topology. It has four network operating mode, they are up, down, relay and promotion. This paper also present the function and composing, message format, main technical guide line, working flow, as well as the design for information transmitted channel of air-air data link.According to the communication protocol of system the network simulation software OPNET are used for modeling and simulation of air-air data link, to establish a more standardized network model, node model and process model. And database, Ftp, Telnet and other operations in a more rational configuration. With flow-based simulation method for joining network, downlink broadcast communication, relay communication. Analyze the simulation results suggest to achieve the basic function of air-air data link. Verify the channel throughput and utilization and other performance guide line for data link.
