STAGE 5G: Optimization of Routing and Wireless Resource Allocation in V2X Communications based on SDN Architecture

In this thesis, the routing and OFDMA wireless resource allocation problems will be jointly addressed for

connected vehicles. The objective is to maximize the satisfaction of requested Quality of Services (QoS)

(i.e., bandwidth, loss rate, latency and jitter) of V2X communications. It is worth noting that V2X

encompasses the communications from Vehicles to Vehicles (V2V) and Vehicles to Infrastructure (V2I).

In addition, we will consider the 3rd Generation Partnership Project (3GPP) standard (Release 14). In fact,

the Initial Cellular V2X standard has been completed recently (i.e., March 2017). However, the problem

addressed in this thesis is still open.



The entire control plane will be hosted in a Software Denied Network (SDN) controller. In doing so, the

global and centralized view in each macro-cell will help to optimize better the satisfaction of QoS.

However, new challenges must be considered such as the i) Southbound API and ii) Monitoring of the

network. In this thesis, we will deploy realistic SDN controller (e.g., ONOS, ODL, etc.) within the 3GPP

vehicular network environment.



The problem complexity studied in this thesis is known as NP-hard. The objective is to propose new

optimization algorithms, which i) minimizing the gap between optimal and generated solutions and ii)

converging in predefined duration calibrated with respect to the 3GPP Release 14. Also, the whole

proposal will be validated with a network environment simulator (e.g., OAI, NS3,
