摘　　要：移动自组网(MANET)是无固定基础设施的无线网络,具有多跳、拓扑结构动态变化、带宽、能量有限等特点。因此常规的地址配置方案,如动态主机配置(DHCP)并不适于MANET。MANET中的节点可以借助IPv6的自动配置机制,利用MAC地址或随机号来自动配置其地址。文中对几种基于IPv6的MANET单播地址自动分配方案进行了讨论,从地址唯一性、简单性、适应性、健壮性等方面进行了综合比较。对移动自组网的地址分配方案提出了一些建议,并指出了进一步研究的问题。Mobile ad hoc network （MANET） is an infrastructure-free wireless network, and has some characteristic features, including highly dynamic, limited power and bandwidth. Thus, the conventional address allocations, such as Dynamic Host Configuration Protocol（DHCP）, could not adapt to MANET. Ipv6 defines autoconfiguration mechanisms, and the nodes are allowed to construct addresses based on the MAC address or random number. In this paper, several representative solutions based on Ipv6 are discussed and compared in uniqueness, simplicity, scalability and robustness. Moreover, some suggestions are proposed and several issues for further study are given.
