【摘要】：当前智能手机应用主要依靠客户端-服务器计算模式,仅仅将手机当作瘦客户端,通过蜂窝网络把感知信息发往服务器进行处理,这使蜂窝网络成为瓶颈,影响了应用的总体性能。提出一种可以直接在手机上运行的分布式流处理系统MobiStreams。该系统可以把计算任务从远程服务器转嫁给本地手机,缓解了蜂窝网络的压力。另外,该系统通过设计的检测点策略有效解决了在智能手机上部署DSPS系统所面临的容错问题。利用部署在美国和新加坡的两个实际应用进行性能评估,结果表明从服务器平台迁移到智能手机平台解决了蜂窝网络的瓶颈问题,使吞吐量提升0.78~42.6倍,延时降低10%~94.8%。
[Abstract]:At present, the application of smart phone mainly depends on the client-server computing mode, only regards the mobile phone as a thin client, sends the perceptual information to the server through the cellular network, which makes the cellular network become the bottleneck. The overall performance of the application is affected. A distributed streaming processing system (MobiStreams.), which can run directly on mobile phones, is proposed. The system can transfer computing tasks from remote servers to local mobile phones, easing the pressure on cellular networks. In addition, the system solves the fault-tolerant problem of deploying DSPS system on smart phone effectively through the design of detection point strategy. Two practical applications deployed in the United States and Singapore are used to evaluate the performance. The results show that migrating from server platform to smart phone platform solves the bottleneck problem of cellular network, increases throughput by 0.7842.6 times, and reduces latency by 10%.
