Abstract:

The rise of 5G Tactile Internet has attracted enormous attentions from the communication society for low latency applications, such as Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communications in intelligent transportation systems, which have already been considered as key use cases of the Tactile Internet. In the current practice, there are two leading solutions for vehicular communications: 802.11 p standardized by IEEE, and LTE-V suggested by Chinese mobile service providers and car manufacturers. With the pros and cons from both ends, it is feasible to leverage both 802.11p and LTE networks in order to fully exploit their advances. In this paper, we investigate low-latency vehicular communications in L TE-802.11p hybrid networks. In particular, we propose a novel vertical handoff protocol for seamless switching between 802.11p and LTE networks. We first study Quality-of-Service (QoS) characteristics of LTE and 802.11 p networks for vehicular communications with extensive simulations in NS-3, and develop a new model to reveal the relationship between communication delay and vehicle's position. Based on this model, we develop the proposed protocol for seamless handoff between 802.11p and LTE networks aiming at minimizing the communication delay in vehicular communications. Simulation results confirm the efficiency of the proposed handoff protocol.
