Abstract: Applying network mobility (NEMO) over proxy mobile IPv6 (PMIPv6) provides a seamless handover between the NEMO network and the PMIPv6 network.However,all packets addressed to mobile nodes are delivered via the local mobility anchor (LMA),leading to large packet delivery overhead.A scenario of distributed NEMO management over PMIPv6 network was proposed to improve the NEMO network quality of service in the vehicles like buses.The data plane of LMA is distributed and the control plane is managed by the central mobility database.By numerical analysis,in short-bus-riding scenarios,the proposed scheme has an advantage in network performance with less network cost.
