A Novel IP Address Auto-Configuration Scheme for MANET with Multiple Gateways

A mobile node who wants to communicate to the nodes in the Internet must firstly be configured a global IP address. The existing schemes have different drawbacks. A novel IP address auto-configuration scheme for MANET with multiple gateways is presented in this paper. It can provide the mobile node with MANET-local address and global IP addresses and guarantee that these addresses configured by this scheme are unique within the MANET. The proposed scheme can be applied to any scale MANET with lower complexity and lower overhead. Because of the existing of multiple gateways, the mobile node can change one global IP address to another quickly if one is not useable. It supports frequent network partitioning and merging, and can efficiently resolve address conflicts in a timely manner whenever they occur.
