Research Area:  Vehicular Ad Hoc Networks
Vehicles moving at high speed in Vehicular Ad Hoc Networks (VANETs) may change the network topology arbitrarily. The mobility patterns followed by the vehicles in VANETs play an important role in the scalability performance of routing protocols and can be classified into mobility models, each of which is defined by their own unique features. In this work, we investigate the impact of three important mobility models on the scalability performance of the well-known Hybrid Location-Aided Routing (HLAR) protocol that has been enhanced by the inclusion of a location verification step. The location verification utilises any available sensor data to verify GPS positions reported by the vehicles and is embedded in a stand-alone Location Verification System (LVS). Our results show that despite the enhanced security features embedded, the routing protocol investigated will remain scalable under realistic mobility patterns. Our work is important for many applications within VANETs, including the efficient dissemination of network-wide location sensor data needed for future vehicle applications.
