Integration of high-bandwidth Wi-Fi technology (e.g. 802.11p) and large-scale 4G network (e.g. Long-Term Evolution, shortly for LTE) could offset mutual limitations and provide vehicles ubiquitous Internet available. In this paper, the authors propose a novel vertical handover algorithm, and a feasible integrated architecture of heterogeneous 802.11p and LTE technologies through comparing Received Signal Strength (RSS) from both interfaces. They perform extensive simulations to investigate and analyze the performance of the proposed architecture using NS3. Results show that the proposed architecture behaves with the high throughput and low round trip time.
