Central Management and Tree Based Auto-configuration in MANET

Nowadays, IPv6 address system has been proposed since nearly ten years ago, the most attractive trait of this address system is the address auto-configuration. But all of these technologies are based on the wired network. In wireless network, especially in the ad hoc network, because of its dynamic and self-organized trait, auto-configuration is very difficult and complex. So in this paper, we try to propose a new mechanism for the auto-configuration in MANET. It is mainly based on the tree structure to generate the unique sequence number for each of nodes to guarantee the address conflict free. In order to avoid the DAD (duplicate address detection), we import three root managing nodes. Each of them just handles one of three part of the whole of network and function some process, such as detecting the node which departs the network abruptly, initiating root managing node election, and managing the network merger. In the following, we will describe them in detail.
