A New Manipulation Based Mobility Model for Vehicular Delay Tolerant Networks
In realistic vehicular communication systems, network connections suffer from dynamic mobility and random operations of independent nodes. End to end fully connected path may never exist. VDTNs (Vehicular Delay/Disruption Tolerant Networks) achieve tolerably timely packet delivery by utilization of asynchronous relays among mobile nodes. Mobility pattern has a strong impact on the performance. Unrealistic or unreasonable mobility model may mislead the design and research. In this paper, a driving manipulations based mobility model is proposed to simulate the trajectory of mobile nodes of multi-hop VDTN networks. The proposed model can generate smooth and reasonable trajectory which resembles the real world driving behaviors. It can also output most results of existing models and can be a general option for a wide range of applications. Simulation is conducted to validate the design.
