| With the continuous development of Internet technology and the popularity of mobile communications, People involved in a more flexible way to keep the Internet and enterprise networks. Mobile IP technology came into being and development, because of the shortcomings of existing Mobile IPv4. Mobile IPv6 is bound to replace it as the mainstream technology in mobile IP applications. However, in Mobile IPv6 applications, there are still some problems, such as voice data transmission, the header of Mobile IPv6 is too big, the transmission efficiency is not high, and the response time is too long trips, that impact such applications in the deployment of Mobile IPv6.In this paper, two kinds of mobile IPv6 communication transmission with application of Header Compression was proposed, one was to transmit compressed header packet on the wireless links at the two ends of the link in the transmission, at the starting point of wireless link the packet header is compressed, and the packet header is decompressed at the end point of the wireless link, hearer compression is not processed in cable network, another option is to transmit compressed header during the whole transmission, and establish end-to-end compression context, in the cable network the compressed header packet is transmitted through the tunnel to improve transmission efficiency.In this paper, we did simulation experiments on two cases above and the case without header compression with NS-2 software, and we compare the transmission delay and efficiency in different cases, the results show that the time saving in transmission can balance off the overhead from header compression and decompression , in transmission contrast to the case without header compression, the two ends compression transmission can improve efficiency by 7.8% and the end-to-end compression transmission can improve efficiency by 10.7%, the quality of service of Mobile IPv6 can be improved greatly. |
