Abstract

IETF has projected Mobile IPv6-based Network Mobility (NEMO) basic support protocol (BSP) to support network mobility. NEMO BSP inherits all the drawbacks of Mobile IPv6, such as inefficient routing path, single point of failure, high handover latency and packet loss, and high packet overhead.. This inefficiency dictates a scheme to enhance QoS within NEMO environment and combining cross-layer mobility management and resource allocation design to reduce latency and packet loss during handovers. This scheme called Hi-NEMO, which is designed for all-IP networks. When a vehicle travels in the network mobility service domain, the hierarchical design and the cross-layer designed protocols offer fast QoS provisioning for the mobile network in the vehicle. The function of the MR is simplified, and an MNN can use its applications and even security mechanism without modification in the mobile network. Implementing analytical models to analyze and compare the performance of HI-NEMO and NEMO BSP shows that HI-NEMO enhances the performance of network mobility compared to NEMO BSP such as handover delay, End to End transmission, packet loss and throughput.. The vehicle mobility has a direct impact on the performance valuation of various network mobility protocols because of that we compare the performance of the two protocol in two mobility models ,randomly straight model and realistic city model called City Section Mobility model(CSM).
