1Micro-Mobility Solution Based on Intra-domain multicast and Congestion Avoiding for Two-Nodes Mobile IP Network

Abstract—In this paper, we deal with micro-mobility in TWINBOARD network, which is a two nodes mobile network architecture based on an all IP infrastructure. The two nodes are the Base Station (BS) and the Access Gateway (AG). To manage micro-mobility, we propose a new approach providing efficient and smooth handover, while being able to coexist and inter-operate with exist-ing technologies. Specifically, we propose an intra-domain multicast-based handover approach combined with an Alert mechanism. Alert approach is a distributed mecha-nism that provides routers with information regarding the congestion state of other routers without any modifications on existing routing protocol. Our solution achieves an efficient intra-domain handover and avoids flooding in the network. The simulations used to evaluate our scheme and compare it to other multicast scheme- DVMRP (Distance Vector Multicast Routing Protocol) show that our solution presents a good performance and outperforms DVMRP scheme. Our main contribution consists on an efficient new approach to manage IP micro-mobility using intra-domain multicast with alert mechanism
