The Li-Fi paradigm that aims at implementing indoor communications links in indoor scenarios, paid attention to the downlink so as to grant connectivity and illumination to several users in very small cells, also known as attocells. However, few work has been done to face the problem of uplink since the use of visible light that send signals from floor to ceiling can be harmful for human eye. In this work we consider the performance offered by an infrared uplink access essentially based on TDMA.

We develop traffic management and data networking mechanisms and study their integrated design for an autonomous transportation system. The traffic management model involves a multi-lane multi-segment highway. Ramp managers regulate admission of vehicles into the highway and their routing to designated lanes. Vehicles moving across each lane are organized into platoons. A Platoon Leader (PL) is elected in each platoon and is used to manage its members and their communications with the infrastructure and with vehicles in other platoons.
