摘要
针对普适环境下移动IP协议的局限性,将集智能性、移动性、安全性等诸多特性于一身的移动代理引入普适计算,详细地阐述了实现过程并进行性能分析与仿真实验。结果表明,普适移动设备在引入移动代理后,能够快速平滑地实现切换,从而大大减少了切换延迟和传输过程中的状态信息量,降低了移动设备在切换期间的丢包率,有效地改善了网络的性能。
Aimed at the limitation of mobile IP protocol in pervasive environment, mobile Agent is introduced, which is intelligent, mobile and secure, to pervasive computing, the applying process is explained in detail, the performance is analyzed, and simulation experiment is realized. The results show that with the introduction of mobile Agent, the pervasive mobile devices can switch smoothly and swiftly, hence reduce handoffdelay and the status information in the process of transmission, lower the loss ratio in the process of the handoffofthe mobile devices and effectively improving the performance of network.
