摘要
HMIPv6是一种有效的微移动管理协议。当移动节点进入一个域时,它会选择一个MAP进行注册。针对HMIPv6的特点,提出了一种支持负载分担的MAP选择算法。该算法利用MAP的优先级值来表征其负载情况,并根据MAP负载的变化,动态调整其优先级值。此外,还将速度因素引入了MAP协议开销的计算。模拟结果表明,该算法实现简单,开销管理和负载分担效果好。
HMIPv6 is an efficient micro-mobility protocol in IP networks. When a mobile node enters in a new domain,it will select a MAP for local registration. According to features of HMIPv6, this paper presents a new MAP selection scheme supporting load balance. The scheme use MAP＇s preference value to characterise the load on that MAP. It also can adjust MAP＇s preference value dynamically as MAP＇s load changes. Besides that,this paper uses speed as a parameter for protocol overhead calculation. The simulation shows that the proposed scheme is easy to implement and achieves good performance in overhead management and load balance.
