The topological ordering algorithm sorts nodes of a directed graph such that the order of the tail of each arc is lower than the order of its head. In this paper, we introduce the notion of covering between nodes of a directed graph. Then, we apply the topological orderingalgorithm on graphs containing the covering nodes. We show that there exists a cut set withforward arcs in these...

Solutions for indoor localization have become more critical with recent advancement in context and location-aware technologies. When wireless sensor network (WSN) used in complex indoor environment, great propagation loss will be caused and it is very difficult to estimate adaptively the location of target nodes when environment changed. In this paper, an indoor adaptive localization algorithm ...

This paper presents accurate estimation of signal activity at the internal nodes of CMOS combinational logic circuits. The methodology is based on stochastic model of logic signals and takes correlations and simultaneous switching of signals at logic gate inputs into consideration. In combinational logic synthesis, in order to minimize spurious transitions due to nite propagation delays, it is ...

Wake-up receivers are the natural choice for wireless sensor networks because of their ultra-low power consumption and their ability to provide communications on demand. A downside of ultra-low power wake-up receivers is their low sensitivity caused by the passive demodulation of the carrier signal. In this article, we present a novel communication scheme by exploiting purposefully-interfering ...

We present a robust multiple-channel vector-matching localization approach (MCVM) based on signal strength difference (SSD) fingerprinting of ZigBee Network. Compared with some existing algorithms, our presented approach has threefold advantages: firstly, far fewer numbers of received signal strength (RSS) measurements and reference nodes are needed; secondly, it shows more robustness to the fl...

Recent developments in machine learning algorithms are playing a significant role wireless communication and Internet of Things (IoT) systems. Location-based services (LBIoTS) considered one the primary applications among those IoT applications. The key information involved LBIoTS is finding an object’s geographical location. Global Positioning System (GPS) technique does not perform better ind...

in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...
