基于NDIS中间层驱动的自组织网头压缩算法实现

Implement of Header Compress Algorithm in Ad hoc Network Based on NDIS IMD

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。

The implement of header compression algorithm in Ah hoe IMD can greatly increase the transmission efficiency of VoIP packets. An IP/UDP/RTP header compress algorithm for the use of Ad hoe network is firstly introduced in this article, then based on the discussing of the data process flow in Ad hoe network test bed, the data process flow is amended and the header compress algorithm is applied in IMD. In succeed, through compare, we analyze the transmission performance of header compress algorithm for timing VoIP packets.
