摘要: 多级HMIPv6网络中移动锚点(MAP)的选择对切换性能有着重要的影响[2][7][8][9]。为了在多级移动IPv6网络中更好的支持移动多媒体业务,本文提出了一种基于最小平均切换时延的MAP选择机制(MAHD-MS)。通过对切换流程的分析和移动节点的移动行为的建模,导出了平均切换时延的估算公式,进而设计了MAHD-MS的流程,并借助NS-2[12]模拟器验证了该机制的有效性。

Abstract: In multi-level HMIPv6 networks, the handover performance greatly depends upon selection of the MAP[2][7][8][9]. This paper proposes a novel MAP selection scheme based on minimal average handover delay (MAHD-MS). By analyzing the handover procedure and modeling the mobility pattern of mobile nodes, we deduce an equation for estimating the average handover latency, and then design the procedure of MAHD-MS scheme. Through extensive simulations with NS-2 simulator, we demonstrate the effectiveness of MAHD-MS scheme.
