Abstract
With the popularity of wireless devices, the possibility of implementing vehicular safety applications has been studied for years in the context of vehicular ad-hoc networks. Dedicated Short Range Communication (DSRC) is designed to serve the needs of vehicular safety applications. However, DSRC does not offer good enough coverage and range in highways for certain applications. Considering these drawbacks, LTE, an advanced cellular communication technology, is proposed as an alternative to DSRC. One problem is LTE capability to support regularly transmitted cooperative awareness messages due to high delay. Within this context, in this paper we propose a mechanism that uses a clustering approach in order to improve the wireless communications while using DSRC for intra-cluster communication and LTE for inter-cluster-communication. We show that our proposition improves the network performance while increasing the data packet delivery and decreasing the average delay.
