Abstract :
To evaluate and further develop communication protocols for transportation systems, new mobility models are required. Especially models covering the needs and specialities of trains and other track-bounded mass transportation systems are not easily available. These models play a critical role in the evaluation of hybrid and other overlay networks in which routing and handover depend on the preferences and QoS requirements of the mobile device. Here velocity and mobility play an important role, e.g. fast moving devices should not be handed over to very small cells, if possible. In this paper we present a mobility model for high-speed trains. This model is used in combination with other mobility models for cars and pedestrians to evaluate the accuracy and usefulness of different localization methods. Thereafter a special localization method for high-speed trains is proposed. This is used to evaluate the quality of a location-based hybrid handover protocol.
