Implementation and evaluation of a network-controlled mobility management protocol (IP2MM): performance evaluation compared with mobile IPv6

The 3G mobile network IMT-2000, was launched some years ago and multimedia traffic in the mobile Internet has been increasing with the growth of wireless access links. Next-generation networks need to efficiently transport huge volumes of multimedia traffic with high-quality mobility management. We have proposed an IP-based IMT network platform (IP²) for the next-generation mobile network architecture and have studied its mobility management scheme, IP² mobility management protocol (IP²MM). IP²MM is a network-controlled mobility protocol that deploys mobility functions inside the network and conceals IP mobility from the mobile node. It is also designed to satisfy the requirements of mobile operators. In this paper, we introduce an overview of IP²MM and show the comparative evaluation results with mobile IPv6. For the evaluation, we implemented both in our experimental system and compared their performance. The results show that IP²MM provides better mobility performance than mobile IPv6, and we conclude that IP²MM is an effective and feasible mobility protocol for the next-generation networks of mobile operators.
