By saving network traffic and improving application throughput, Multicast becomes a pervasive traffic pattern in data centers. Reliable transmission is an important requirement in Modular Data Center. In this paper, we proposed a reliable multicast approach for EBSN, a modular data center structure. For efficient transmission, multiple multicast trees were constructed. To realize reliable, we chose...
In this paper, we propose a context-aware distributed data storage mechanism to optimize the performance of reading/writing in the emerging mobile cloud computing environment. In particular, the exploited context information including user mobility pattern, network condition, and data access preference (intensity to read and write/update). The context information is utilized to improve the efficiency...
We improve data access efficiency in mobile cloud storage by exploring users' context information. Specifically, we optimize data reading and writing on mobile devices from/to distributed cloud storage according to network condition, user mobility pattern, and data access preference. We propose a Reed-Solomon erasure code based context-aware distributed storage system. Then, a mixed integer linear...
In this paper we study the problem of optimal task scheduling that minimizes the computation and AC energy consumption of a data center. Different from existing studies that assume a linear relationship between computation power consumption and CPU frequency, our model considers a nonlinear cube-function computation power model. Compared with the linear model, this model better describes the behavior...
In this study, build interactive location database intelligent video car recorder system. Video automotive logger system was established in the iOS intelligent mobile devices (iPhone). The video car recorder system can be record the current driving conditions, display the current location on the map, and upload it to the location database. Location database is constructed by a network server, MySQL,...
