The document proposes a collaborative content delivery scheme for software-defined heterogeneous vehicular networks (SD-HetVNETs) consisting of cellular base stations (CBSs) and roadside units (RSUs). It defines utility models for CBS, RSU, and vehicles to motivate cooperation. A double auction game is used to achieve agreement between CBS and RSU for multicast-assisted content delivery to maximize their utilities. Simulations show the scheme enhances utilities of all participants and network efficiency. Hardware requirements include a Pentium IV 2.4 GHz system with 40 GB hard disk and 512 MB RAM, while software requirements include Windows, Java/J2EE, MySQL, and NetBeans 8.1.

Collaborative Content Delivery in Software-Defined Heterogeneous
Vehicular Networks
Abstract:
The software definedheterogeneousvehicularnetworks (SD-HetVNETs), which consist of cellular base
stations (CBSs) and roadside units (RSUs), have emerged as a promising solution to address the
fundamental problems imposed by the surge increase of vehicular content demand. However, due to
the everincreasingrequirementof the vehicles’ quality of experience (QoE) and the network vendors’
utilities,there come new challengestomotivate CBStocooperate withRSUfor contentdeliveryinorder
to maximize their utilities and improve the efficiency of the networks. Therefore, in this paper, we
propose a collaborative content delivery scheme to improve the utilities of the participants (i.e., CBS,
RSU and vehicles) in the SD-HeVNETs, where the CBS can cooperate with RSUs by serving a group of
vehicles with multicast technology. We first define the utility models to map the profits of the
participantsin the networks and formulate the utilities of CBS and RSU as two optimization problems.
Then, we exploit the double auction game to motivate CBS to cooperate with RSU for the multicast
assisted content delivery to address the two maximization problems. Next, the optimal bidding
strategies of CBS and RSU in the game are analyzed when the Bayesian Nash equilibrium is achieved.
With the optimal bidding strategies, both CBS and RSU can bid for the multicast assisted content
deliveryservicestomaximizetheirutilitiesbasedonthe networkstatus.Finally,the performance of the
proposed cooperative scheme is evaluated by using simulations. The simulation results demonstrate
that the utilities of all the participants in the networks can be enhanced and the efficiency of the
networks can be improved.

Proposed System: , we propose a scheme to motivate CBS to cooperate with RSU for multicast assisted vehicular content deliveryinthe SD-HetVNETs.Specifically,by consideringthatCBSmay refuse tocooperate with RSU due to the resource costs, we define the utility functions to map the profits and costs of CBS, RSU and vehicles,respectively.The distributedprofitscanthusmotivate CBStotake part inthe multicastassisted contentdeliveryprocessefficiently.Inthisway,the QoEof vehiclesin the networks can be guaranteed. After that, a double auction game is formulated to model the interaction between CBS and RSU for achieving the agreement and distributing the profits, where the optimal bids of CBS and RSU are analyzedbasedonthe networkstatus.By finding the Bayesian Nash equilibrium of the double auction game, both CBS and RSU can obtain their maximum utilities and the efficiency of the networks can be improved at the same time. The contributions of this paper are three-fold System Model: In the SD-HetVNETs,the RSUand CBS are onlyin charge of deliveringcontentstovehicles.The control decisionsare made bythe SDN controllerwhichhasthe globe view of the networks.Inthisway,the controllerinthe control plane makesdecisionsandthe RSUand CBS in the data plane delivercontent basedon the commandpublishedbythe controller.If anRSU cannot serve all the vehiclesinits coverage,the controllerwillstartthe double auctionprocess.If the agreementbetweenthe RSUand CBS inthe auctionisachieved,the CBSandRSU will provide vehicleswithcontentsbasedonthe content deliverycommanddeterminedbythe SDN controller.Accordingtothis architecture,we thenmodelthe SD-HetVNETswiththe followingcomponents.
