this paper state the issue related to mobile cloud computing for real-time video streaming. Recently the media streaming particularly video streaming becoming very popular among the users of hand held devices. Due to exponential growth in mobile device users, mobile network is facing large traffic of video signals. Due to this growth of users, video streaming especially real-time video streaming is now an interesting area of research. To increase the streaming speed and quality of real- time video a lot of work and progress is being done in hardware architecture of mobile devices. We have multi-core processors and enough memory space in modern mobile devices. The concept of GPU is also introduced in mobile devices to overcome the problem of speed in video data processing. But very less work is done to utilize the capability of these devices through parallel architecture development for real-time video streaming process. So it is the matter of discussion and research that how the computational and memory power of these devices can be utilized through parallel computations to speed up the process of video data up to ultra high speed. Mobile cloud computing environment can play an important role in this field. So In this paper, the review of architectural and QoS issues in mobile cloud computing environment for real time video steaming are being presented. There are many real-time video streaming techniques for mobile devices, some possible parallel architecture and QoS (Quality of Services) issue to leverage the architecture capability of the mobile cloud computing environment for these real-time video streaming is being discussed in this paper. Keywords—QoS; Video streaming; Mobile cloud computing; A mobile device; GPU; Parallel algorithms I. INTRODUCTION
