应急通信中异构网络切换优化过程仿真

Simulation on Optimization of Heterogeneous Network Switching Process in Emergency Communication

研究异构通信网络流畅的切换过程可保证正常通信。应急通信异构网络在面对多通信对象时,为了满足不同对象的需要,需要实时切换网络,以保证数据对接,当数据流量较大时,切换过程需要进行用户确认,比较耗时。传统的应急通信异构网络通信过程中的网络数据量较大,在一些复杂的通信过程中,多用户参与通信,为了保证多用户同时通信的要求,需要频繁切换网络,多次切换浪费大量通信时长,将造成应急通信延迟。提出基于多层次解析融合算法的应急通信过程中异构网络融合通信方法。采集应急通信过程中的异构网络中的信号,利用离散GTBP优化窗口对所有的网络信号进行依次扫描,计算上述网络信号的拉普拉斯能量和,对网络信号进行多层次解析,计算不同网络信号层次的权重,实现应急通信过程中异构网络融合。实验结果表明,利用改进算法进行应急通信过程中的异构网络融合,能够极大的提高应急通信的效率。

An integrated communication algorithm for heterogeneous network in emergency communication is presented based on the multilevel resolution fusion algorithm. Signals in the heterogeneous network in the process of emergency communication are gathered, all network signals are in turn scaned by using the discrete optimization GTBP window, the sum of the Laplace energy of network signals is computed, the network signals are analysed in multi-lev- els, the weights in different network signal levels are calculated, and the heterogeneous network integration in the process of emergency communication is realized. The experimental results show that the proposed algorithm can greatly improve the efficiency of emergency communication.
