Research On The Networking Technology Of Aviation Data Link

As the air force is more and more important for the national defense, every country pays much attention in the study of Aviation Data Link.A variety of high-performance aviation data link is also endless. As the aviation data link network has a dynamic network topology, non-center self-organization and multi-hop networking features, etc., coupled with the modern battlefield for data confidentiality and secrecy requirements, aviation data link networking technology, based on the directional antenna and the Ad hoc technical, also become a research hotspot.Since the introduction of directional antennas, both receiver and sender arrange their antenna in the straight line to communicate normally.It is diffcult to complete neighbor discovery in the stage of initialization without topology information.In addition,as the high speed in the aviation data links ,it is necessary to have a quick the node enter/quit network plan and the synchronized plan.Therefore,in this paper,combined with the cutting-edge development of the current aviation data link of networking technology,aviation data link networking technology is researched deeply.The overall framework of the network and the structure of MAC frame are designed.This paper proposes network initialization plan based on the directional antenna and ad hoc technology, the node enter/quit network plan as well as the synchronized plan.Finially, aviation data link network is modeled and simulated using the OPNET network simulation software. Theoretical analysis and simulation results from two aspects demonstrated the feasibility of the scheme.Results show that the designs meet the technical specifications and system requirements.
