| 摘 要： | 研究分级移动IPv6协议中移动节点的移动性能和数据通信情况对移动锚点（MAP）选择机制的影响，将MAP按覆盖范围分成不同等级，提出了一种通过计算移动节点的移动性能和数据通信量，使移动节点按照移动性能的升降和通信量的变化，动态选择不同MAP级别的机制，达到减少移动节点的切换次数和均衡MAP之间负载的目的。模拟实验证明动态选择MAP级别的机制，减少了绑定更新消息，并在MAP的负载均衡方面取得良好的效果，达到了减少移动节点的切换次数和均衡MAP之间负载的目的，优化了移动节点的移动切换过程，是一个适应性很强的分级选择MAP的机制。

| Abstract: | In the hierarchical mobile IPv6（HMIPv6）,the influence of mobile nodes＇mobile performance and the status of data communication on Mobile Anchor Point（MAP） selection mechanism are studied,the MAP is divided into different grade based on area,and by computing the mobile performance of mobile nodes and communication quantity,advance the mechanism of selecting dynamically different MAP grade based on the change of mobile performance and communication quantity,in order to reduce handover times between mobile nodes and balance load between MAPs.Simulation shows that the mechanism of selecting dynamically different MAP reduce binding update,the good effect of load balance for reducing handover times between mobile nodes and balance load between MAPs,optimize handover process between mobile nodes. The hierarchical selective MAP mechanism is charactered by strong adaptability. |
