Effective implementation of location services for VANETs in hybrid network infrastructures

In this paper we propose and evaluate a heterogeneous architecture for location service in vehicular environments. The proposed Location Service utilizes the infrastructure of cellular networks to offload the Dedicated Short Range Communication (DSRC) systems from the signalling overhead required for the location service. We evaluate the performance of such a hybrid solution in terms of overhead and end-to-end delay. The results suggest that a...
