Abstract

MobiCoStream, an acronym for Mobile Collaborative upStream, refers to Real-time video upstream of captured video in Mobile Augmented Reality (MAR) applications. MAR for tele-assistance deals with providing real-time assistance to the user through the power of Augmented Reality. Real-time applications have strict delay requirements which need to be met in order to satisfy the user Quality of Service (QoS). Mobile communication still being in its third generation, limits the availability of high up-link bandwidth for video transmission. The problem is tackled by means of Bandwidth Aggregation through which the hand-held devices in the vicinity, collaborate with the user to achieve real-time video up-link and maintain the user QoS. In this paper, we present the actual results pertaining to the prototype implementation of the proposed system. Also presented are some simulation results, by viewing the multiple hand-held devices as a virtual Multiple Input Multiple Output (MIMO) system and in turn considering the popular Alamouti scheme in this context.

MobiCoStream:移动增强现实应用的实时协同视频上游

MobiCoStream是移动协同上游(Mobile Collaborative upStream)的缩写，指的是移动增强现实(MAR)应用中捕获视频的实时视频上游。远程援助MAR通过增强现实的力量向用户提供实时援助。实时应用对延迟有严格的要求，为了满足用户的服务质量(QoS)，需要满足这些要求。移动通信仍然处于第三代，限制了视频传输的高上行链路带宽的可用性。解决这一问题的方法是通过带宽聚合，使附近的手持设备与用户协同实现实时视频上行，并保持用户的QoS。在本文中，我们给出了与所提出系统的原型实现有关的实际结果。通过将多个手持设备视为虚拟的多输入多输出(MIMO)系统，并在此背景下考虑流行的Alamouti方案，给出了一些仿真结果。
