With the popularity of Internet of Things, the next logical step will focus on the application layer on top of network connectivity, especially Web of Things. While most of the existing efforts on Web of Things are focused on device mash up and data collection, in this paper a semantic web of things framework is proposed to leverage Semantic Web as the unified mechanism for monitoring, tasking, presentation,...
It is well known that the electromagnetic (EM) waves do not propagate well in road tunnels. The channel characteristics for empty tunnels have already been well analyzed by both theoretical and numerical/experimental methods. However, any road tunnels are full with running vehicles. Currently a few works have investigated the influence of the vehicles on the signal propagation in road tunnels. However,...
Wireless networks can greatly facilitate the communication in underground mines and road/subway tunnels, where the propagation characteristics of electromagnetic (EM) waves are significantly different from those in terrestrial environments. According to the structure of underground mines and road tunnels, two types of channel models can be utilized, namely, tunnel and room/pillar channel models. However,...
The propagation characteristics of electromagnetic (EM) waves in tunnels are significantly different from those in terrestrial environment. However, the current tunnel channel models cannot provide an analytical solution for both near and far region of the sources. In this paper, the Multimode model is proposed to completely characterize the wireless channel of tunnels in roads/subways as well as...
Aiming at intensive data processing in grid environment, a grid platform IDPGP is constructed based on Globus Toolkit 4, OGSA-DAI, Condor and PBS. This platform mainly provides grid information acquirement service, grid resource management service, data access and integration service, which can realize grid resources sharing, intensive data access and processing. In the grid resource management service,...
