Container-based virtualization offers several advantages such as high performance, resource efficiency, and agile environment, which can make IoT device management easy. Though previous studies introduce container-based virtualization to IoT devices, they do not address different network modes of containers and the performance issues. Because the network performance is an important factor in IoT,...
As the rapid increase in mobile data traffics, radio-over-fiber(RoF) technology is one of the possible candidates for wireless signal distribution over fiber optic links. With the combination of wavelength division multiplexing (WDM) passive optical network (PON)s RoF technique has raised great interests because it provides a large number of high capacity mobile data channels on a single optical fiber...
We demonstrated centralized optical routing based on the digitized RoF technique for wireless back-haul networks. The digitized RoF system showed constant performance with EVM (3.75%) while the performance of analog counterpart is highly dependent on optical link conditions.
The optical properties of both phytoplankton and zooplankton were investigated in this study. The absorption spectrums of planktons were measured using an UV-visible spectrophotometer. An absorption peak was found at 670 nm for the phytoplankton. A particle detecting system for an optical plankton counter (OPC) was designed and built with a red LED as a light source based on the optical characteristics...
