Data Broadcasting on Cloud-VANET for IEEE 802.11p and LTE Hybrid VANET Architectures

Vehicular Ad-hoc Networks (VANET) is an unique category of Mobile Ad-hoc Network (MANET), which promises prospect in the future Intelligent Transporting System by providing inter-vehicle communication of road surveillance, traffic information, road condition etc. However, the high nodes mobility, frequent network change topology, unstable network and small coverage issues in the VANET implementation motivates for a stable design of cloud clustering algorithm. This paper propose a system that combines the traditional 802.11p standard VANET networks with LTE networks to form a hybrid Cloud-VANET that provides low network overhead with a high mobility management and high coverage in VANET networks. This approach enables VANET to have high bandwidth along with uninterruptable data connectivity by reducing the data packet loss and SNIR loss ratio over the network. The OMNET++ and SUMO traffic generator has been used to simulate the network scenario. Simulation results indicates that hybrid VANET architecture improve the overall network stability and performance.
