Abstract:

For UAV（Unmanned Aerial Vehicles） group air to air data link of wireless communications, in accordance with the ZigBee protocol, through the establishment of slot polling table the slot allocation is completed. After a brief analysis of the ZigBee protocol stack layers of functionality and the use of the network topology based on a focus on the data link protocol air to air data link slot allocation mechanism and the network address allocation mechanism. Discuss how to use OPNET（Optimized Network Engineering Tools） network simulation tool to create this model of wireless communication protocol process, and by constructing a network simulation platform for the channel access delay, throughput, etc. of the simulation analysis to verify this air to air data link communication protocols used the validity of this simulation for other network protocols as a reference.
