摘　　要：对移动终端的行为特性(主要包括移动特性及服务特性)进行分析建模,确定总体性能目标,然后综合考虑上层可达移动锚点(MAP)间的负载均衡,提出了一种多目标协作的自适应MAP选择策略(A-MAP)。基于NS-2网络仿真平台,考虑具有不同移动速率的移动终端的比例配置,设计了一组实验场景,并选择了3种典型的MAP选择方案作为比较对象。通过调整会话到达率验证了A-MAP方案在系统开销、负载均衡以及平均切换时延方面均有较好的性能表现。In HMIPv6 networks with multi-level MAP architecture, it remains a significant challenge to select an optimal serving MAP for the mobile terminal to optimize the whole network performance. By analyzing and modeling the behavior characteristics of the mobile terminals, mainly including the mobility characteristics and the service characteristics, the overall performance objective is determined. Then, an adaptive MAP selection strategy with multi-objective cooperation is proposed （A-MAP）, in which the load balancing among the available upper-layer MAPs is comprehensively taken into account. Considering the proportional allocation of mobile terminals with different velocities, a set of experimental scenarios is elaborately designed based on the NS-2 network simulation platform, and three typical MAP selection strategies are selected for the comparison. The performance efficiency of the proposed A-MAP on system cost, load balancing, and average handover latency is verified by adjusting the session arrival rate.
