The emerging Internet of Things (IoT) connects the physical world to the digital one and composes large networks of smart devices to support various applications. In order to provide a suitable communication in such networks, a reliable routing protocol is needed. In this paper, a modified version of an IPv6 Routing Protocol for Low-Power and Lossy networks (RPL), which has been standardized by...

Abstract— In this paper, input impedance of a vertical rod under lightning stroke is first computed by applying the method of moments (MoM) on the Maxwell’s equations. The circuit model is then achieved through applying modified vector fitting (MVF) on the computed input impedance. After then the equivalent circuit is again extracted for a few values of soil conductivity and rod radius. Finally...

In this paper we propose an accurate and fast numerical method to obtain scattering fields from lossy dispersive inhomogeneous planar layers for both TE and TM polarizations. A new method is introduced to analyze lossy Inhomogeneous Planar Layers. In this method by applying spline based Galerkin’s method of moment to scalar wave equation and imposing boundary conditions we obtain reflection and...

in this paper, intelligent water drop algorithm (iwd) is used to analyze single overhead line connected to grid-grounded arrester. in this approach, at first norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (mom) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. finally applying inte...

We consider lossy counter machines, i.e. counter machines with counters whose contents can spontaneously decrease at any time. They are not Turing-powerful, since reachability is decidable for them, but they still have interesting undecidable properties: For a lossy counter machine it is undecidable if there exists an initial connguration s.t. there is an innnite run. Lossy counter machines can...

in this paper, shielding effectiveness (se) of a perforated enclosure with imperfectly conducting walls is evaluated. to this end, first, an accurate numerical technique based on method of moments (mom) ispresented. in this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. then, the impedance boundary condition on the imperfectly conductin...

The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...

In this report, we propose lossless/lossy coding gain as a new objective criterion to theoretically evaluate lossless and lossy coding performance of the lossless/lossy wavelet (LLW). The proposed lossless/lossy coding gain consists of three parameters: “lossless coding gain”, “quantization-lossy coding gain” and “rounding errors”. Performances of 15 kinds of the LLW are measured with two-dimen...

Lossy VASS (vector addition systems with states) are deened as a subclass of VASS in analogy to lossy FIFO-channel systems. They can be used to model concurrent systems with unreliable communication. We analyze the decidability of model checking problems for lossy systems and several branching-time and linear-time temporal logics. We present an almost complete picture of the decidability of mod...
