We present VENICE, a project that aims at developing a high-fidelity, high-performance, and highly-controllable experimental platform on commodity computing infrastructure to facilitate innovation in existing and futuristic network systems. VENICE employs a novel model-driven network emulation approach that combines simulation of large-scale network models and virtual-machine-based emulation of real...
In mobile environment, when downloading and opening learning resources it would need the large data communications bandwidth and strong data processing ability. Due to the intrinsic limitations of a mobile environment, there can be long time latency for a data access. Data prefetching is an approach to this problem. in this paper, a improved data prefetching strategy was proposed. based on existed...
Image fusion could process and utilize the source images, with complementing different image information, to achieve the more objective and essential understanding of the identical object. In order to implement image fusion on a real-time embedded system, a proper algorithm must be considered. A novel image fusion scheme based on biorthogonal wavelet decomposition is presented in this paper. As for...
Software Radio (SR) is an emerging paradigm of the wireless communication system design due to its flexibility and adaptability. However, the implementation of SR platform is always challenging, especially for high date rate transmission such as up to 1Gbps. Although general-purpose processor(GPP) based SR platform can take full advantages of Software Radio, the performance is often limited due to...
The CyberWorkstation (CW) is an advanced cyber-infrastructure for Brain-Machine Interface (BMI) research. It allows the development, configuration and execution of BMI computational models using high-performance computing resources. The CW's concept is implemented using a software structure in which an “experiment engine” is used to coordinate all software modules needed to capture, communicate and...
The decision of receiver buffer length is very important for real time streaming media. Different buffer length get different quality of playback even under the same network circumstances such as algorithm of transmission and playback. Due to the importance of receiver buffer for the streaming media, in this paper we study the principle of buffer and design on a buffer simulation platform of real-time...
Weakly hard real-time application requires that scheduling algorithm should provide service satisfied QoS parameter, so a new fixed-priority scheduling algorithm with (m,k)-firm guarantee is presented. It assigns scheduling priority of task based on period and QoS parameter, and the task is switched between preemptive state and optional state to reflect its pressure. Schedulability test inequation...
