%X Vehicular networks create new opportunities to develop innovative and enhanced solutions for generating reliable communication among vehicles. To widely deploy vehicular networks, it is needed to overcome several existing research challenges in such networks. Guaranteeing data transmission is one of the main challenges in vehicular networks that are specified by their large scale and high mobility. Recently, the effective deployment of femtocell networks inside high speed moving vehicles, in order to improve the quality of data transmission, is an interesting topic for researchers. In this paper, we propose a novel handover scheme utilizing coordinated multiple point transmission (CoMP) in high speed moving vehicular femtocell networks. The proposed scheme aims at a seamless, deployable, and efficient handover procedure for this specific environment. We take into account signal-to-interference-plus-noise ratio (SINR) and outage probability to evaluate the performance of our proposed handover scheme. 1. Introduction Vehicular network is a new type of wireless network that has appeared along with the development in wireless technologies and the automotive industry. Vehicular networks are spontaneously formed among moving vehicles, which are equipped wireless interfaces in homogeneous or heterogeneous technologies, and infrastructure components. Compared to other communication networks, the vehicular networks have some attractive features, such as unlimited transmission power, higher computational capability, and predictable mobility of vehicles [1¨C3]. In recent years, a special type of mobile ad hoc network (MANET), called as vehicular ad hoc network (VANET) [4¨C6], is considered in vehicular environments. The VANET supports two types of communications, including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. The characteristics of VANETs require distributed solutions that strongly depend on the vehicle density, the communication range, and the interference range of neighbor vehicles. Regarding V2I communication, in inside-vehicle environments, cellular users face difficulties in receiving high-speed services due to low-quality signals from the outdoor base stations (eNodeBs). Femtocell has been considered as a new technology to overcome the drawbacks of cellular wireless communications in indoor environments. Femtocell has many advantages, such as improved coverage, low power, improved SINR (Signal-to-Interference-plus-Noise Ratio) level, low cost, reduced infrastructure and capital cost, and improved throughput [7¨C11].
