NEW EFFICIENT TRANSMISSION TECHNIQUE OF VEHICLE ORIENTED TO BURST SERVICE

摘要

Concerning on highly efficient transmission of amounts of burst service in the Space Information Network (SIN), which easily happens during the process of disaster relief, the paper proposes a highly efficient transmission algorithm based on data priority. The algorithm includes probability division of network data and distribution of drop probability on the basis of burst level, thereby solving the problem that important and time-sensitive data are easily discarded because of jam. We discuss the new algorithm in the condition of ideal buffer and fixed buffer, and simulation results show that the algorithm has obvious advantages in end-to-end delay, throughput and burst processing efficiency, which has important implications for disaster relief and other emergency communications.
