Simulation And Analysis Of Dynamic Time Slot Allocation Algorithm For Data Link

With the continuous improvement of the process of modernization and the growing development of weapons and equipment,more and more sophisticated weapons appear on the rapidly changing battlefield.Air fighters,fighter planes,early warning aircraft,land tanks and armored vehicles,naval ships and submarines and other strategic weapons,and coordinating data communication among all kinds of arms become a strategic hit.Different from the past,modern warfare requires a communication system not only to control information transmission,but also the interaction of target information and battlefield situation a lot of information,the information required to achieve efficient,accurate and real-time strategy in exchange for sharing data based on data link as a typical communication system,completed the task of great significance in modern war.At present,the major military powers in the world are developing their own data links,among which the Link Series in the United States is the most famous.Early Link-4,late Link-11 and Link-16,Link-22,and the TTNT in the experimental stage,among which Link-4,Link-11 and Link-16 are more mature.Link-16 has been equipped with large scale troops.Therefore,this topic focuses on Link-16.In view of the urgent demand of the data link of modern war and the rapid development of national data link,through the study of Link-16,this paper proposes an improved slot allocation algorithm--IPD-TDMA(Improvement dynamic-TDMA,)using OPNET simulation software of the algorithm by modeling and simulation.Collect the relevant data of Link-16 and TDMA,familiar with the relevant background and significance;analysis of several typical TDMA algorithms,compares the advantages and disadvantages of several algorithms;on the basis of the realization process of the algorithm,formulated the implementation scheme of IPD-TDMA algorithm;modeling and simulation,verified the output curve;finally has carried on the simple analysis and comparison.The focus of this paper is to propose and implement the algorithm.Based on Link-16,taking dynamic TDMA as the research object and using OPNET simulation software as tool,the dynamic usage of TDMA slot is realized,and the adaptability and reliability of Link-16 are enhanced.This paper firstly introduces the Link-16 network architecture,introduces the traditional slot allocation algorithm,and compares the advantages and disadvantages of each other;then it introduces the TDMA algorithm;then put forward the improved IPD-TDMA algorithm,the background and the implementation process;finally use the OPNET algorithm to carry out the modeling and analysis.Through the verification and analysis of the algorithm,it is proved that its performance is expected to achieve the desired results,which lays a good foundation for the next stage of research.
