摘要
我国内河航运非常发达,同时随着船联网的兴起,内河航运发展也越来越迅速。本文针对船联网中异构网络的垂直切换技术进行研究,分析异构网络之间垂直切换的一般流程和关键技术,提出一种基于灰色理论的垂直切换信号预测算法。并通过试验仿真分析,验证该算法的正确性。此算法可以应用于实际中对船载终端的异构网络的垂直切换和同构网络的水平切换。
The domestic rivers' transportation is very prosperous, at the same time with the rise of the ship networking,inland river shipping is also growing rapidly. According to the vertical handoff in heterogeneous network in ship networking research, analyzed the general process and key technology of vertical handoff between heterogeneous networks, proposes a prediction algorithm for vertical handoff signal based on Grey theory. The correctness of the algorithm is verified by experimental simulation analysis. This algorithm can be applied to the vertical handoff of heterogeneous networks and the horizontal switching of homogeneous networks.
