QoS-Enabled Improvements for the Network Mobility Protocol

The aim of this article is to introduce an approach to providing connectivity on public transport connecting to the wider Internet via heterogeneous networks and prioritizing traffic according to service classes. We present a packet prioritization for each service class: premium, intermediate and default. A railway scenario is considered as our case study to evaluate the prioritization mechanisms. Experiments using the NS-2 simulator are to implement and evaluate the model. Results are presented to show the effectiveness of the model for network mobility in heterogeneous environments.
