Vehicular networks are a cornerstone of the envisioned Intelligent Transportation System (ITS) by enabling vehicles to communicate with each other via Vehicle-To-Vehicle (V2V) communications to overcome the current and future needs for increasing traffic safety and efficiency. In this paper, they employ the Knapsack Problem (KP) to formulate the problem of cooperative scheduling and radio resource management in vehicular networks for non-real time services. For the sake of Maximizing Sum Utility (MSU) of the networks, they propose two-dimensional-multi-choice knapsack problem (2D-MCKP)-based scheduling scheme to select the coordinator vehicles for the sink vehicle and allocate radio resource to V2V and Vehicle-To-Infrastructure (V2I) links to solve the MSU optimization problem.
