The Study Of Distributed TDMA Wireless Access Control Protocol

Link16is a relatively new data link, its existing tactical data link capability certain technical and operational improvements, and the lack of some other data link data exchange, and to be able to achieve significant improvements. TDMA access protocol used in the Link16data link networking, the no center TDMA networking requires a reasonable allocation of the resources of the slot. Network planning, including the selection of an appropriate network structure, to determine the network parameters and the planning of the network time slot, the planning of the network time slot is also the most difficult, what kind of distribution scheme, how to design access algorithm to become one of the key technologies.This study is the Link16data link, Link16is a center TDMA (Time Division Multiple Access:TDMA) networking.This Paper introduces the Link16TDMA access technology to analyze the slot allocation method, rational and effective allocation of resources slot on the timing meet certain constraints, a simple description of the algorithm; Second, based on queuing theory based on the the article detailed description of the queuing system and the data network queuing theory, in the analysis under the assumption that the service capacity of the system and the amount of the delay mathematical deduction, analyze the mathematical process of node generates packets, Overview network important performance and simulation parameters; then, the article Link16data chain network performance line simulation based on OPNET network simulation platform to build Link16-node model, node model the important processes and state analysis, analysis of running the simulation results; Finally,the paper relies on specific laboratory projects completed with TDMA access the kind of radio-based semi-physical simulation, analysis and design through the semi-physical simulation interface, the actual radio TDMA mode with the principle, the configuration of the slot allocation scheme Learn more access during transmission of data packets.In this paper, a distributed TDMA access control method has more detailed research, through specific engineering practice to master it works, after study and work deep significance.
