RESEARCH_ON_END-TO-END_HANDOFF
说明: 本文在研究IEEE802.16e协议和SIP协议的基础上,提出了利用
SIP解决IEEE802.16接入网络中端到端切换的新方案。该方案采用跨
层切换的设计思想,联合MAC层和应用层SIP协议,在底层链路切换
的同时,完成应用层会话的修改,加快了切换过程,减少了切换时延,
提高了切换成功率。本文基于NS2仿真平台,完成了相应的仿真平台
搭建过程,实现了SIP协议模块和WiMAX协议模块的融合,扩展了SIP
协议模块的部分消息,最终在基于SIP协议模块和WiMAX协议的统一
NS2平台上实现了基于WiMAX接入、支持SIP扩展功能的SIP会话建
立和修改过程。

FOAGRNN
果蝇优化算法优化灰色神经网络。对不起各位,打包的时候忘记把数据打包进去了。这数据是个25*3的矩阵。前两列数据为{0,1}之间,同一排,若前两个数有一位小于0.5,则第三位为1.否则为0.如此组合25组数据。(FOA gray neural network optimization.)
