Research On Data Transmission Sublayer Protocol Of Shortwave Wireless Communication

Shortwave communication has been used for more than a century,until today,it still plays an important role in the communication network.In order to interface with modern communication protocols,solutions must be designed to facilitate data communication via high frequencies.Many countries and other countries have jointly formulated the corresponding short-wave wireless communication protocol.Such a solution defines a unified standard for accessing short-wave communication wireless networks and it is a layered protocol suitable for high-frequency radio data communication.Its data transmission sub-layer protocol provides a data transmission rule,the study of this layer protocol is a key step to realize the short-wave wireless communication protocol.Therefore,the realization of the data transmission sub-layer protocol is a problem to be solved for the short-wave wireless communication protocol to ensure the effective and reliable transmission of data.First of all,the article studies the detailed analysis and research of the data transmission sublayer protocol,the protocol mainly achieve data transmission through the data transmission method,data frame format,data segmentation and reorganization and transmission status.Aiming at the problem that the segmented frame length has a certain impact on the protocol transmission system,an optimal segmented frame length solution is proposed,which effectively improves the transmission efficiency in the communication process and reduces the overhead of bit resources and protocols.Secondly,the study of the problem of data coverage and loss that may occur in the peer sublayer of the receiving node for larger data and multiple segmented data,through multiple tests,it has been found that a method of developing a data buffer area preprocessing module can be used.This method solves the problem of data coverage and loss caused by excessive data and multiple segments,thus enhancing the reliability of data transmission.Finally,the protocol is divided into multiple modules for design analysis,and the implementation methods of some modules are compared to obtain a relatively prominent method suitable for engineering applications.According to the design scheme,the VC++6.0 tool was used to simulate under the Windows system environment.The data transmission of the two-node and multi-node data transmission sublayer protocol was completed,and the effectiveness of the best segmented frame length scheme and the data buffer area were verified The role of the pre-processing module.And conducted multiple tests in the wireless communication environment to verify the feasibility and correctness of the design scheme.
