“…In future work we will consider adding more dual processor threads and making threads dependent on each other and because the issues that brought by the intricacy of communication between various applications and underlying Quality of service architectures (Qos) [18], which reduces the usefulness of QoS provisioning, so, idea for future work trying to increase the benefit of Qos by incentivizing threads in real time systems.…”

One of the issues with multi-threading in operating systems is the concurrency of operations or threads. In a multithreaded process on a single processor, the processor can switch execution resources between threads, enabling concurrent execution. Concurrency indicates that more than one thread is making progress, but the threads are not actually running simultaneously. The switching between threads occurs rapidly enough that the threads might appear to run simultaneously. In this paper, three related strategies for prioritizing multi-threading are presented: ACE-thread, Semaphore coprocessor, and the Concurrent Priority Threads Algorithm. The aim of this work is to enhance an existing prioritization algorithm, specifically the Concurrent Priority Threads Algorithm, by extending a dynamic slicing algorithm to prioritize multi-threading concurrently. The algorithm is designed to compute correct slices in multi-threading prioritization scenarios. Threads with the same highest priority can perform in a synchronized manner without encountering deadlocks. The C++ programming language is used to implement the extended algorithms. The improved algorithm achieved results that were 3% more accurate than the existing one. The outcomes of this work would facilitate the simultaneous execution of threads with the same priority, ultimately reducing waiting and processing times.

“…The work in this paper thoroughly investigates the OoS for these three services in several simulation scenarios. In our previous work [30], we compared wireless communication models with IntServ, DiffServ, and IntServ-DiffServ services and discussed the difference in their performance. In this paper, we proceed to evaluate QoS mechanisms thoroughly based on communication performance improvement under multi-homed networking and fluctuating resource availability and how to merge these mechanisms within the communication network to ensure the delivery of the optimal end-to-end QoS to the users.…”

The paper introduces a reliable system, providing a sufficient solution for the associated nodes during hand-offs. • It investigates different QoS mechanisms, deploying each mechanism into various interfaces, and overall network performance when nodes switch between available interfaces. • It compares overall performance and feasibility of QoS mechanisms with the single-homed and multi-homed networks/nodes (site/host multi-homing) fluctuating resource availability.The user's hand-off is still an arguable issue that many mobile communication systems face, especially with the exploded growth of users and internet-based applications. Hence, there is a critical need for adequate quality of service (QoS) to meet the stringent requirements. This paper aims to study the overall performance and feasibility of several QoS mechanisms with the single-homed and multi-homed networks/nodes fluctuating resource availability. It investigates the adaptability of multi-interfaced multi-homed techniques to enhance the essential governing parameters, i.e., throughput, end-to-end latency, processing time, and jitter. Moreover, the paper introduces an interface selectivity technique for the multi-homed node to adopt the optimal interface, which offers the best services to explore the enhancements of the overall network performance. The overall results show how the introduced mechanism managed to keep the communication going on the multi-homed node. Furthermore, the results show that site multi-homing provides a better overall end-to-end latency over host multi-homing as it supports the entire network.

“…Oleiwi and Al-Raweshidy studied in their recent work [28] the contribution of EH and other key enabling technologies to enhance system performance, considering a relatively similar concept with a simplified system of single-input single-output (SISO) scheme equipment. However, our previous papers [29,30] investigated the impact of the multihoming principle on improving system reliability, operational efficiency, and the overall performance. The value of multihoming management was addressed to keep communication going for the multihomed user, in addition to presenting an interface selectivity technique.…”

In this paper, cooperative simultaneous wireless information and power transfer (SWIPT) terahertz (THz) multiple-input multiple-output (MIMO) nonorthogonal multiple access (NOMA) are considered. The aim is to improve wireless connectivity, resource management, scalability, and user fairness, as well as to enhance the overall performance of wireless communications and reliability. We optimized the current wireless communication systems by utilizing MIMO-NOMA technology and THz frequencies, exploring the performance and gains obtained. Hence, we developed a path-selection mechanism for the far user to enhance the system performance. The EH SWIPT approach used to improve THz communications performance was investigated. Moreover, we proposed a reliable transmission mechanism with a non-LoS (NLoS) line of THz communications for open areas or any location where the intelligent reflecting surface (IRS) cannot be deployed, in addition to using the cheap decode-forward (DF) relaying instead of IRS. The performance and scalability of the upgradeable system were examined, using adjustable parameters and the simplest modulation scheme. The system presents a noticeable improvement in energy efficiency (EE) and spectral efficiency (SE), in addition to reliability. Accordingly, the outcome showed an improvement in the overall reliability, SE, EE, and outage probability as compared to the conventional cooperative networks of the recent related work (e.g., cooperative MIMO-NOMA with THz) by multiple times with a simpler design, whereas it outperformed our previous work, i.e., cooperative SWIPT SISO-NOMA with THz, by more than 50%, with a doubled individual user gain. This system reduces the transceiver hardware and improves reliability with increasing transmission rates.
