Localization information of individual nodes is crucial for many advanced functions including routing, querying in wireless sensor networks. Most of the existing localization algorithms in wireless sensor networks are designed for outdoor environment and few of them can get a reasonable localization precision in indoor environment. This paper presents a(More)
In this paper, a facile method was presented to synthesize tin dioxide (SnO2) nanowires by solvent-free method using SnCl2 x 2H2O as precursor and mesoporous silica SBA-15 as the hard template. No solvent was used in the processing. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), energy dispersive(More)
The stunning increase of video streaming has been a major part of the network flow in the past few years. It is essential for content providers to manage more flow servers to satisfy the demands of users. Therefore, to effectively manage large-scale servers and to identify problems, service node become crucial to guarantee video user experience. The(More)
