In this paper, we propose a user centric bandwidth allocation scheme for low latency data transmission in ultra dense vehicular networks. Various mobile devices such as mobile phones, sensors of vehicles or autonomous driving systems,require low latency and bandwidth intensive packet delivery between the devices and the Internet aiming to support real-time applications. In the ultra dense vehicular network, small base stations (SBSs) are densely deployed in a fixed geographic area to provides higher date rate. In further, each SBS cooperates with others to form clusters to better support seamless wireless data transmissions, and each mobile device dynamically plans its wireless connectivity for data transmission when it moves in the network. Specifically, each mobile device pre-allocates the amount of bandwidth from a cluster, formed by several SBSs, based on its expected movement, the delay and band-width requirement of the packet transmission and the resource availability of each cluster. Moreover, to effectively utilize the available network resource, each cluster also redistributes its residual bandwidth to the mobile devices pre-allocate bandwidth from it. Consequently, the latency of the data transmission can be better sustained in the ultra dense vehicular network.
