摘要
通过研究专用短程通信(DSRC)协议栈中的应用层部分,针对其中的ASN.1 PER编解码模块,设计并实现了一种编解码框架,框架包括ASN.1映射规则、通用编解码流程以及符合小设备应用的内存管理机制。良好的模块划分使得此框架具有较好的通用性。测试结果表明,此实现框架具有良好的性能,满足协议的实时性要求。
Based on the study of the application layer of Dedicated Short Range Communication （DSRC） protocol stack, as for the ASN. 1 PER encoding and decoding module, a framework for encoding and decoding was designed and implemented, which included ASN. 1 mapping rules, a general procedure for encoding and decoding, and a memory management method specifically designed for small devices. The framework is of good generality because of well-organized modules. The test results show that the framework has good performance, and it meets the real-time requirement of the protocol.
