Research and simulation of unknown protocol identification method based on carrier network

舰载网络通信中,由于舰船的自组织特性和过往船只的不确定性,通常会受到未知协议的通信求情,对舰载网络中的未知协议有效识别,提高舰载网络通信链路存活性和稳定性。目前舰载网络未知协议识别采用的是端口路由分层识别方法,存在通信信号传输的保真度不好,路由开销大等问题,提出一种基于高阶谱包络调制的舰载网络中的未知协议识别方法。构建舰载网络通信的系统模型,对舰载网络进行路由分簇设计,对舰载网络通信中的未知协议进行多接口多信道的自组织网络分配,采用高阶谱包络调制方法对通信信号进行特征提取和动态融合,实现对舰载网络中的未知协议的优化识别。仿真结果表明,采用该算法能有效实现舰载网络中的未知协议的特征提取和识别,提高了通信链路的存活时间,降低舰载网络通信的误码率。

Shipborne network communication,due to the self organizational characteristics and passing ships uncertainty in ship,usually by the communication protocol is unknown to intercede,the carrier network of unknown protocol to effectively identify,improve activity and stability of the shipborne Network communication link. At present,the identification of the unknown protocol in the carrier network is a method for the identification of the port routing hierarchy,which is the problem of the high fidelity of the communication signal transmission and the high routing overhead. The system model of ship borne network is constructed,and the network is designed. The unknown protocol is distributed in the carrier network.The high order spectrum envelope modulation method is adopted to extract the communication signal and realize the dynamic fusion. Simulation results show that the proposed algorithm can effectively achieve the feature extraction and recognition of unknown protocol in the carrier network,improve the survival time of the communication link,and reduce the error rate of the carrier network communication.
