| Vehicular Ad Hoc network (VANET) is a special technology in wireless ad hoc networks. It can be used to provide road safety, efficiency and traffic organization in transportation system. Thus, new applications arise in several fields such as traffic engineering, traffic management, dissemination of emergency information in order to avoid critical situations, comfort, entertainment and other user applications.;IP multimedia Subsystem (IMS) is a subsystem, standardized with Third Generation Partnership Project (3GPP). The IMS supports heterogeneous networking with Quality-of- Service (QoS) policy. The goal of this platform is to integrate All-IP services and to provide final user with multimedia services such as voice, data and video with appropriate billing mechanisms. With the advent of the IP Multimedia Subsystem, it is desirable to provide VANET end-users with IMS services. However, characteristics of VANET cause major challenges to control the performance of IMS services. On the other hand, the traditional IMS core network faces a set of problems such as centralized control, low efficiency and poor scalability of core equipment, compared with the IT environment using Cloud Computing. Cloud Computing is an emerging paradigm in the field of information technology. In this new paradigm, dynamically scalable and often virtualized resources are provided as services over the Internet. The migration of IMS to cloud can improve its performance. This project proposes an innovative architecture in order to integrate VANET, IMS and Cloud Computing. |
