The technology of route optimization for NEMO based on DHCPPD

The basic NEMO protocol results in a sub-optimal route between Mobile Network Node (MNN) and Correspondent Node (CN). This paper provides a mechanism based on DHCP Prefix Delegation (DHCPPD) to enable Mobile Network Node (MNN) to perform route optimization with CNN which has basic MIPv6 support. The goal is to use DHCPPD to assign Care-Of-Address (COA) to MNN, MNN can bind with Correspondent Node (CN) with basic MIPv6 support [3]. It effectively reduce unnecessary large travelling route and overhead, thereby enhance the performance. The solution is effective for both single NEMO and nested NEMO for which we will deploy DHCP replay mechanism as extension, and has a better performance than the basic NEMO protocol.
