摘要
主要研究如何解决在无线移动物联网中使用IPv6所引起的传输效率以及移动切换中数据连续传输问题。为传输效率问题,提出了IPv6报头的复合压缩方法,使用了地址分配器、比较编码、Lempel-Ziv-Welch编码器等算法对报头作压缩处理。为实现移动切换时的数据连续传输,提出了改进的移动切换协议E-FHMIPv6方法。仿真结果证明,该算法和方法提高了传输效率,在移动切换时降低了丢包率。因此,提出的解决方案对移动互联网的性能有明显的提高。
This paper resolved the problems including transfer efficiency and mobile seamless induced by adapting IPv6 in wireless internet of things.Based on RF4944 draft,the compound solution for transfer efficiency.It is composed of address assigning,comparator encoding and Lempel-Ziv-Welch encoding algorithm.Based on FHMIPv6,present an improved mobile switching protocol,presented E-FHMIPv6,for mobile seamless transfer.The simulation results show that these solutions can improve the performance of transfer efficiency and mobile switching effectively.Thus,the solution improves the performance of mobile Internet of things obviously.
