“…In the case of satellite networks, considering the round-trip time of approximately 500 ms for geostationary satellites, the system's performance is very poor. [18] D. Diversity Slotted ALOHA An alternative solution allows for reducing latencies and retransmitting the packet multiple times without waiting for the acknowledgment. Such a technique is known as "Diversity Slotted ALOHA" (DSA).…”

This article focuses on enhancing random access methods in wireless communication systems through the introduction of the physical layer network coding technique. Specifically, we delve into the "Contention Resolution Diversity Slotted ALOHA" (CRDSA) protocol, an innovative method based on physical layer network coding and interference cancellation techniques. Our primary objective is to provide an in-depth comparison between traditional protocols such as ALOHA, Slotted ALOHA (SA), and our CRDSA method.In this article, we elaborate on how our CRDSA method outperforms these traditional protocols. We demonstrate concretely that our method significantly enhances channel efficiency, reducing collisions and increasing the overall system throughput. We also present meticulously studied results from our experiments, highlighting CRDSA's superior performance in terms of throughput and packet loss rates.In summary, our study makes a significant contribution by introducing CRDSA as an innovative and effective solution for wireless random access systems. The results clearly demonstrate that our method surpasses traditional approaches, paving the way for significant improvements in wireless communication networks.

This study provides a worthwhile method for increasing the magnetic field energy and induction machine (IM) effectiveness. The coupling between the transmitter and receiver windings in the IM system can be improved by creating materials with specific electromagnetic properties. This added material has altered the magnetic flow as well as the energy of the magnetic field. Eventually, it is possible to calculate the efficiency of the magnetic field, or the ratio of primary to secondary magnetic energy. With the use of two-dimensional finite element analysis, numerical results on five cases with various configurations of a magnetic substance have been produced. This material, which varies in length or breadth, is positioned close to the windings of the transmitter, receiver, or both. Case 3, in which the transmitter generates a magnetic field on the receiver side with a minimum energy of 0.05 J and a maximum energy of 0.015 J, is the ideal material configuration for DC current. Currently, the system efficiency is 0.29 on average. A 1 kHz transmitter's energy is constant under all conditions, but its counterpart's energy fluctuates significantly, with case 5 receiving the most energy. Therefore, case 5 turns into the optimal structural arrangement. It can be inferred that case 5 similarly dominates the other with an efficiency of 0.0026, which is much greater than that of 1 kHz efficiency, while the windings are operating at 1 MHz. This leads to stronger magnetic field coupling and increased power transfer effectiveness.

“…Moreover, according to [9], different modulation schemes have diverse IDET performance. Therefore, an adaptive modulation based IDET transceiver was firstly investigated in [12], which significantly increased the attainable rate-energy region. In [13], the non-orthogonal multiple access (NOMA) technique was adopted by a transmitter by superimposing the modulated symbols destined to multiple WDT requesters in the powerdomain.…”
