An integrated architecture for multi-homed vehicle-to-infrastructure communications

We develop an intelligent distributed quality-of-service (QoS) control scheme which inter-operates between mobile routers, managing vehicular networks mobility, and road communication gateways (RCGs). This scheme manages vehicle-to-infrastructure (V2I) communications by enabling multi-homed vehicular networks to evenly distribute traffic among egress links of their mobile routers based on vehicular communication policies, available bandwidth and performance metrics of selected routing paths with correspondent nodes (CNs). In this scheme, the data control plane is considered as a collaborative entity and specifies detailed operations to be performed in the mobile routers and RCGs. Simulation experiments show that our proposed scheme can improve the congestion window (CWND) of TCP and the e2e packet loss of video traffic, despite network mobility. It also guarantees the service parameter settings of each uplink and downlink connection, while achieving reasonable utilization efficiency of network resources.
