在无线自组织网(AdhocNetwork)中使用头压缩算法可以极大的提高语音业务在自组网中的传输效率。本文首先介绍了适用于自组网的IP/UDP/RTP头压缩算法;然后在分析了Adhoc网测试床数据处理流程的基础上,对测试床的数据处理流程进行了修改,在中间层驱动中实现了该头压缩算法;最后通过比较,分析了头压缩算法的实时话音业务传输性能。
Adopting the header compression algorithm in wireless Adhoc network can greatly improve the transmission efficiency of voice services in ad hoc networks. This paper first introduces the IP / UDP / RTP header compression algorithm which is suitable for ad hoc networks. Then based on the analysis of the Adhoc network test bed data processing flow, the data processing flow of the test bed is modified. In the middle layer driver The header compression algorithm is implemented. Finally, real-time voice service transmission performance of the header compression algorithm is analyzed by comparison.
