在无线自组织网（Ad hoc Network）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Ad hoc 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。关键词：NDIS 中间层驱动自组织网头压缩算法多跳ABSTRACT：The implement of header compression algorithm in Ah hoc IMD can greatly increase the transmission efficiency of VoIP packets. An IP/UDP/RTP header compress algorithm for the use of Ad hoc network is firstly introduced in this article, then based on the discussing of the data process flow in Ad hoc 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.Keywords: NDIS IMD Ad Hoc network header compress algorithm multi-hop
