“…2(a) and 2(c) were used to validate our proposed formalism. For the first measurement configuration, an X-band (8.2-12.4 GHz) waveguide setup [12,13,20] was used to measure S-parameters of a waveguide phase shifter (a non-reciprocal network) loaded with ferrite material from Kearfott company with 𝐿 = 28.7 mm (considered as a two-port device), as shown in Fig. 2(b), using uncalibrated S-parameters of the configurations in Fig.…”

“…Error-corrected scattering (S-) parameters of a microwave two-port device can be obtained by using a proper calibration procedure such as the thru-reflect-line (TRL) [1], multiline TRL [2], and the thrureflect-match [3]. To achieve the same goal, de-embedding line-line techniques can be applied for characterization of S-parameters of a twoport device [4][5][6][7], which is our main concern in this study, in addition to the determination of line impedance [8,9], line propagation constant [10][11][12][13], and complex permittivity/permeability of sample-loaded line [14][15][16][17][18][19][20][21].…”

“… Eq 5 can be further written as Eq 6 . Where d f is the forward delivery ratio, which is the probability that the packet is received at the destination node, d r is the reverse delivery ratio, which is the probability that the ACK packet is delivered or received by the sender node, and τ is the transmission or propagation constant [ 37 , 38 ]. Subsequently, the node energy represented by Eq 7 can be estimated by the Heinzelman first order radio model [ 39 ], see Fig 10 .…”

Routing Protocol for Low-power and Lossy Networks (RPL), the de facto standard routing protocol for the Internet of Things (IoT) administers the smooth transportation of data packets across the Wireless Sensor Network (WSN). However, the mechanism fails to address the heterogeneous nature of data packets traversing the network, as these packets may carry different classes of data with different priority statuses, some real-time (time-sensitive) while others non-real-time (delay-tolerant). The standard Objective Functions (OFs), used by RPL to create routing paths, treat all classes of data as the same, this practice is not only inefficient but results in poor network performance. In this article, the Prioritized Shortest Path Computation Mechanism (PSPCM) is proposed to resolve the data prioritization of heterogeneous data and inefficient power management issues. The mechanism prioritizes heterogeneous data streaming through the network into various priority classes, based on the priority conveyed by the data. The PSPCM mechanism routes the data through the shortest and power-efficient path from the source to the destination node. PSPCM generates routing paths that exactly meet the need of the prioritized data. It outperformed related mechanisms with an average of 91.49% PDR, and average power consumption of 1.37mW which translates to better battery saving and prolonged operational lifetime while accommodating data with varying priorities.

A microwave method is proposed to determine the forward and backward propagation constants (γ + and γ − ) and the wave impedance (z w ) of reciprocal and non-reciprocal microwave networks whose positions are not known within their measurement cells (position-insensitive). The proposed method relies purely on analytical expressions and can also evaluate the reference plane transformation distances. Scattering parameter measurements at the X-band (8.2-12.4 GHz) of a reciprocal network (a waveguide straight) and a non-reciprocal network (a microwave phase shifter) arbitrarily positioned into their measurement cells were conducted to retrieve γ + , γ − , and z w for validation of our method and testing its position-insensitive property. The importance of the method becomes apparent when compared to conventional methods whose accuracy is based on precise determination of the reference planes.
