摘　　要：HAW II是IP网络中的一种微移动协议.随着节点在域内不断移动,HAW II需要不断变更移动节点到域网关的路径.针对HAW II的特点,本文提出了一种基于D efau lt R ou te的路径更新算法DRB,该算法在充分考虑各种网络环境的基础上,将defau lt rou te用于HAW II的路径更新过程.模拟结果和相关计算表明,该算法在保持与原有算法相近性能的条件下,具有更大的灵活性,并有效降低了路由表的开销.HAWII is a mieromobility protocol in IP networks. Mobile hosts need to change their path to the gateway while moving within the domain. According to features of HAWII, this paper presents a path re-establishment scheme based on default route DRB. Taking into account different network environments, this scheme uses default route in path re-establishment proeedure. The simulation and derivation show that DRB achieves more flexibility and decreases the routing table overhead while keeping similar performance.
