Future 4G cellular networks are featured with high data rate and improved coverage, which will enable realtime video multicast and broadcast services. Scalable video coding is very appropriate for wireless multicast service because it allows to choose different modulation and coding schemes (MCSs) for different video layers and can provide good video(More)
Inter-cell interference mitigation is a key challenge in the next generation wireless networks which are expected to use an aggressive frequency reuse factor and a high-density base station deployment to improve coverage and spectral efficiency. In this work, we consider the problem of maximizing the weighted sum-rate of a wireless cellular network via(More)
Analytics algorithms on big data sets require tremendous computational capabilities. Spark is a recent development that addresses big data challenges with data and computation distribution and in-memory caching. However, as a CPU only framework, Spark cannot leverage GPUs and a growing set of GPU libraries to achieve better performance and energy(More)
Future mobile broadband networks are characterized with high data rate and improved coverage, which will enable real-time video multicast and broadcast services. Scalable video coding (SVC), combined with adaptive modulation and coding schemes (MCS) and wireless multicast, provides an excellent solution for streaming video to heterogeneous wireless devices.(More)
BACKGROUND Female sex workers (FSW) were high-risk population for HIV and other sexually transmitted diseases (STD) earlier, and now are an important driver of the HIV/AIDS epidemic in China. Sentinel surveillance for FSW was set up to monitor the trend of HIV prevalence and risk behavior-related HIV infection. This study collected the data on street-based(More)
Scalable video coding (SVC), together with adaptive modulation and coding (AMC), can improve wireless multicast streaming video by jointly performing radio resource allocation and modulation and coding scheme (MCS) selection. However, the existing schemes in the literature allocate radio resources for different video layers separately, which leads to a(More)
Many applications in wireless sensor networks like video surveillance have the requirement of timely data delivery. Real-time routing is needed in these applications. Because of the limitation of node energy, energy efficiency is also an important concern in routing protocol design in order to increase the network lifetime. In this paper, we propose a(More)
The P4 language is an emerging domain-specific language for describing the data plane processing at a network device. P4 has been mapped to a wide range of forwarding devices including NPUs, programmable NICs and FPGAs, except for General Purpose Graphics Processing Unit (GPGPU) which is a salient parallel architecture for processing network flows. In this(More)
