Video streaming challenges over vehicular ad-hoc networks in smart cities

Recent developments in wireless technologies and the Internet of things have led to the design of new communication systems such as in Vehicular Ad-Hoc Networks (VANETs). These networks are planned to offer new infotainment applications and traffic safety services with smart equipments in a smart environment. A Smart City is intended as an environment which is controlled and monitored with advanced technologies and new types of communication in order to improve the quality of life with innovative services. One of the major challenges facing smart cities communication is to ensure efficient services delivery under economic, social and environmental circumstances. Hence, multimedia communication and notably video streaming are predicted to be of high benefit for traffic management as well as for providing entertainment and advertising services. With video streaming services, real-time information will be employed and provided by vehicular networks for safety and efficiency goals. In this paper we focus on video streaming transmission over vehicular ad-hoc networks in smart cities. A simulation of urban mobility of vehicles in VANET is tested with SUMO in Kerkennah city map. With this scenario of mobility, we simulate the video streaming transmission over VANET using the NS3 simulator. Experimental results evaluate the performance and the factors that affect video streaming quality in vehicular environments.
