摘要
分析了具有全球连接的移动自组织网络中地址自动配置需要解决的地址唯一性、网络分裂与融合等关键问题,针对现有地址自动配置算法实现复杂、扩展性差、时延过长等不足,设计了一种自组织网络地址自动配置算法。该算法采用代理分配和自主分配相结合的方式,实现初始地址的快速分配,并在路由协议中引入虚拟地址概念,以维护本地地址的唯一性。算法自动发现和选择默认出口网关,由网关分配全球唯一IP地址。所提出的方案具有开销小、实现简单、支持频繁的网络融合和分裂等优点,可适用于拓扑动态变化的自组织网络地址配置需要。
In MANET(Mobile Ad Hoc Network) with global connectivity, an IP address auto- configuration scheme should be able to ensure address uniqueness and deal with problems caused by network merging and partitioning. In this paper a novel address auto - configuration algorithm that works with global connected MANET is designed. A node can be allocated a .local address quickly based on an address agent or by oneself. The virtual address is used to detect address duplieation, which simplifies the DAD (Duplication Address Detection) mechanism. An outdoor gateway is chosen automatically to assign the global address. With the advantage of low overhead and simple operation even under the situation of frequent network partitioning and merging, it is applicable to large- scale MANET.
