摘要
To improve the scheduling efficiency of the tracking and data relay satellite system(TDRSS), most previous work focused on the scheduling models and its algorithms, rather than the translation procedure from the requirements of customers to the input traffic data for scheduling. In this paper, we propose a complete traffic characteristics model that captures the requirements for TDRSS of diversified customers based on the empirical distribution of real traffic. Compared with previous traffic models of TDRSS that concentrated only in the time domain, the proposed model can depict the traffic characteristics in both time and space dimensions. Specifically, the proposed model consists of five main components which are integrated and implemented as the system traffic generator software, whereby multiple types of traffic with different distribution can be accurately generated. Numerical simulations are conducted in two scheduling scenarios which demonstrate the efficacy of the traffic characteristics model. This model can also be used in the computer simulation of the whole system performance as well as the optimization of inter-satellite routing algorithms.
