Abstract:
The ever-increasing number of connected devices and the limited radio resources bring the need of solutions for reliable communications in dense environments.

If communication protocols are not well designed, the wireless dense network suffers from channel congestion problem.

The impact of channel congestion is serious in distributed networks, such as vehicular networks, which need to serve for applications with stringent requirements.

With the objective of improving communication quality in dense mobile environments, we suggested different solutions particularly
1) load balancing in overlapping wireless LANs,
2) distributed congestion control in CSMA/CA vehicular ad hoc networks,
3) CDMA-based vehicular communication and
4) visible light communication for vehicle platoons.

In this work, we present our algorithmic contributions, the mathematical analysis, and the performances evaluated by computer simulations and experiments.
