With the fast development of the cloud computing and virtualization techniques, computation resources can be allocated more dynamically and scalably on demand. This paper aims to study two types of computing, i.e., service computing and communication computing. We have proposed to have both computing resource in mobile operator's mobile cloud and investigated how to jointly allocate them with the...
Fog radio access networks (F-RANs) are becoming an emerging and promising paradigm for fifth generation cellular communication systems. In F-RANs, distributed edge caching techniques among remote radio heads (RRHs) and user equipment (UE) can effectively alleviate the burdens on the fronthaul toward the base band unit pool and the bandwidth of the RANs. However, it is still not clear as to how social...
Recently, commutating resource is playing an increasingly more important role in the user experience and future generation wireless networks, as exemplified by the recent progress in mobile edge computing (MEC) and cloud radio access networks (C-RAN). In this paper, by taking advantage of both C-RAN and MEC, we propose a novel mobile cloud-radio access network (MC-RAN) structure, which is composed...
Taking full advantages of two cloud-based techniques, i.e., cloud radio access network (C-RAN) and mobile cloud computing (MCC), mobile operators will be able to provide the good service to the mobile user as well as increasing their revenue. This paper aims to minimize the mobile operator's cost while at the same time, meet the task time constraints of the mobile users. In particular, we assume that...
Based on geographic information systems (GIS) and remote sensing (RS), five primary factors affecting soil erosion in the ErHai Lake Basin are extracted rainfall erosivity, soil erodibility, terrain, vegetation coverage, and soil and water conservation measures. Meanwhile, the amount of soil erosion is estimated using the revised universal soil loss equation (RUSLE) model. Furthermore, the spatial...
The Tibetan culture is one of the most unique religious in the world, and it has deeply influenced the Chinese culture in many ways. What's more, the Tibetan area in Yunnan Province is important for the world, not only in the nomadic culture, but also in religious culture and Chinese history. With the aid of the current advanced technology, especially the Geographic Information System (GIS) and Virtual...
The land use structure and biological service function of Dian-chi lake watershed are being changed by the rapid development of social economy and urbanization, which finally leads to the generation and aggravation of agriculture and urban non-point source pollution in whole basin. Thereby, it is necessary to study the relationship and spatiotemporal process between human activities and land use/cover...
There are two method frequently used for parallelization: data parallel and task parallel. According to the characteristics of analysis of digital terrain, data parallel is more applied, so Petri nets is introduced in this paper to describe the parallel relationships within data patitions based on granularity model. As for different storage environment, corresponding scheduling algorithms are proposed...
In this article, it is explored that how to design and implement a temporal and spatial early warning model for AIDS spread on sex in Kunming (Yunnan province) by using ABM and making spatial analysis by developing in ArcEngine and ArcSDE. Obviously, the method of integration between ABM models and GIS technology is also clarified as a key technology in the text. As a result, based on a spreading...
Since AIDS was first discovered, mathematical models of the transmission dynamics of this disease have been developed to determine the drivers of the epidemic. It has become apparent that the most important factor in the propagation of the disease is the aggregate effects of individual behavior and perception of risk in a geographic environment. Agent-based models (ABM) allow one to simulate the social...
At the age of post-Kyoto Protocol, international forestry carbon sequestration project not only has strongly achieved the form of harmoniously developing between economy and environment conservancy in developing countries, but also is promoting the relative research on theory and technology in Forestry Carbon Sequestration. And this paper has discussed that how to establish the Geo-Spatial Model of...
BACKGROUD: Since Mexico reported the first case of Influenza A H1N1 influenza patients in March 2009, Influenza A H1N1 flu spreads rapidly around the world and threats seriously to human health. OBJECTVIES: (1) Establishing an Agent-based Model (ABM) of H1N1 transmission, simulating and predicting the distribution of location, extent and development of the law of H1N1 to explore the space-time propagation...
