IoT device are usually built as edge networks in smaller areas, but with the development of technology, more and more areas without infrastructure need to be covered. LEO satellites, due to its full coverage of the Earth and relatively low latency, can provide network access for IoT system. In this paper, we propose a hybrid TDMA MAC protocol LST-MAC for IoT network based on LEO satellite, which can reduce network delay and improve the system scalability. Specifically, we design a geographic priority time slot allocation strategy which can ensure optimal load and delay, besides, we also design a continuous forward time slot allocation strategy, which guarantees real-time data while reducing the utilization of satellite resources. Then we design two algorithms based on both strategies, which can effectively reduce network delay and balance the satellite resources. The simulation experimental results are consistent with the theoretical results, which embodies the effectiveness of the algorithm. |
