针对舰船节点在海域试验通信网中如何选择最优网络接入的问题,提出一种基于层次分析法和逼近最优解排序法的网络接入策略。该算法充分考虑指挥者偏好决策、网络状况、业务需求等主客观因素,并结合位置信息进行改进,根据预测的下一位置处的网络贴近度,比较网络切换的效益与成本。仿真计算表明,该算法能够有效选择理想接入网络,减少网络切换次数,提高试验信息的传输可靠性。
Aiming at the problem that how to select the optimal network in ocean-based heterogeneous test communication network, a network access selection algorithm which based on AHP and TOPSIS was raised. This algorithm considered subjective and objective factors including commanders’ preference, network status and service demand. Furthermore, based on the predicted close degree of the optimal network when the warship node moves to the next location, the algorithm compared the benefits and costs of the handoff process. Simulation results showed that, the method can select the optimal network effectively with fewer handoff times and thus improved the reliability of transmitting the test information.
