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 existing technologies. Specifically, we propose an intra-domain multicast-based handover approach combined with an Alert mechanism. Alert approach is a distributed mechanism 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.
