To get the accuracy of Wireless Sensor Networkboundary node localization and decrease error, this paperpresent an arithmetic on RSSI (Received Signal StrengthIndicator) weighting circulate localization. This arithmetic isbased on RSSI, combination of least squares estimate localizationalgorithm and weighted centroid circulation method. Thealgorithm firstly is introduced into threshold method forscreening...
Node localization of wireless sensor network is a hot topic, but current algorithms of 3D wireless sensor node localization are not accurate enough. In this paper, the DR-MDS algorithm is proposed, DR-MDS algorithm mainly calibrates the coordinates of nodes and the ranging of nodes based on multidimensional scaling, it calculates the distance between any nodes exactly according to the hexahedral measurement,...
Simulations of nanoelectronic devices with nonequilibrium Green's function are computationally very intensive, in particular, when combined with multiband approaches, such as the methods. To reduce the cost and make the simulation of realistic devices tractable, we have developed a model order reduction method for the simulation of hole transport in silicon nanowires using three-...
We present a fast time-domain multiphysics simulation framework that combines full-wave electromagnetism (EM) and carrier transport in semiconductor devices (TCAD). The proposed framework features a division of linear and nonlinear components in the EM-TCAD coupled system. The former is extracted and handled independently with high efficiency by a matrix exponential approach assisted with Krylov subspace...
