Abstract

The evolution of wireless access technologies has led to a new era of Mobile Internet. Network mobility, which considers the mobility of an entire network, is particularly suitable for mobile environments. Efficient network mobility QoS-handover design is essential to meet QoS requirements for real-time communication. In this paper, we propose a cross-layer hierarchical network mobility architecture and protocol, called HiMIP-NEMO, which is designed for all-IP networks. HiMIP-NEMO optimizes the routing between a mobile network node and the correspondent node, and supports fast QoS provisioning in the network mobility service domain. The simulation results demonstrate that Hi-MIP-NEMO reduces handover latency and packet loss, and supports high velocity vehicles.
