This paper researches and analyzes the current situation of the application of mobile medical services in chronic disease monitoring and management. With chronic diseases and mobile medical development trend in China, we propose a monitoring and management system for the physical sign of elderly patients with chronic diseases. By using the system, patient can monitor and upload the physical sign data,...
Real-time deferrable server (RTDS) scheduler is presented since Xen 4.5. Under RTDS, a guaranteed physical CPU capacity is provided to every virtual CPU so that the performance can be better predicted. However, the guaranteed capacity is defined off-line, it might not fit the requirement of a virtual CPU at the run-time. In this paper, an RTDS-based CPU scheduler is proposed, called enhanced real-time...
It is predicted that the global mobile data traffic will increase nearly eightfold in the next five years, and the cloud applications will consist of 90 percent of total mobile data traffic by the end of 2019. There is no doubt that the increasing high quality video requirements and huge similar information stored in cloud servers enforce to setup a new communication paradigm. In this paper, we will...
In order to improve energy efficiency of computation-intensive workloads in Cloud Radio Access Network (C-RAN), virtualized hardware accelerators (HA) are proposed in this paper. In C-RAN architecture, the base stations (BS) are running in the virtual machines. Virtualization mechanism of HA makes each BS feel like owning a HA exclusively, but actually BSs sharing the HAs. To tackle the problem of...
In cognitive radio network (CRN), the utilization of wireless spectrum can be dramatically improved with the secondary user (SU) opportunistically access the licensed channels. With the help of spectrum sensing technology, the SU can dynamically access a large number of spectrum holes. However, how to allocate the spectrum holes between SUs becomes a thorny problem. The utilization of proper allocation...
To alleviate the growing concern of energy waste in networked devices, we propose an energy saving strategy in the ``server-centric" data center network. Focusing on servers, we introduce a basic scheme based on the transition of automata. By changing efficiently from sleeping state to active state in different network traffic, servers save the energy. This scheme is self-adaptive and simple...
The NC machine is a tool which is indispensable in industrial manufacturing. In recent years, with network, computer and other related technical development, It provide a new power to numerical control technology. The main idea of this article is description the networked CNC machine fault diagnosis which based on expert system
Presence service has become one of the key application services, which can be applied in many areas, such as buddy status, tele-working, ticket sale, the Internet of things, location-based service and so on. And cloud computing, widely used to provide a variety of IT services, has been a new method of sharing infrastructure. This paper presents a design and implementation of presence service deployed...
Popular Web sites receive an enormous share of Internet traffic. These sites have a competitive motivation to offer better service to their clients at lower cost. One of the solutions is to using content distribution network (CDN). When we design a CDN we need to find proxy server placement to provide its clients with the best available performance while consuming as little resource as possible. This...
The paper describes a service model for the autonomic management of distributed networked systems. In this model, a service provider (SP) maintains multiple protocol modules to exercise the infrastructure resources under various environment conditions. Each protocol exhibits a certain degree of performance optimality and service resilience in distinct operating regions of the network infrastructure...
