“…The network's nodes' data locations must be known by both static and dynamic nodes. Throughput, energy levels, and packet delivery ratio are the three main factors that affect how well the WSN performs [16][17][18]. The primary objective of the routing protocol structure is to minimize energy consumption by identifying the most energy-efficient routes between the source and the destination.…”

The Restricted Flooding-based Route Discovery (RFBRD) – Particle Swarm Optimization (PSO) routing scheme introduced for Wireless Sensor Networks (WSNs) in this article not only reduces the energy loss due to unwanted RREQ (Route Request) flooding but also improves the lifetime of the network. Excessive flooding depletes energy and affects the lifetime of the network. Nodes in scarce regions are allowed to forward first and subsequent RREQ packets freely in the network and are relocated using PSO to improve their neighborhood for better neighbor connectivity and coverage. Whereas, nodes in the populated region or dense region are governed by energy ratios and are allowed to forward first RREQ packets only when they satisfy the energy conditions. This scheme is efficient in maintaining a proper balance of QoS (Quality of Service) parameters works well for high-density networks for more than 50 nodes and can restructure network topology obtaining better connectivity. Experimental analysis showed that the performance of AODV is superior in the case of a low-density network (N=40 nodes) while RFBRD-PSO outperforms in all other configurations (60, 80, and 100 nodes). The Packet delivery ratio was increased by 0.08% and the throughput was higher by 11 kbps in the case of RFBRD-PSO. The routing overhead is low by approximately 40% and the average end-to-end delay is found low by 0.04 as compared to the AODV routing. The energy residue in the case of RFBRD-PSO is less than the value of AODV is the cost paid for a higher packet delivery ratio. The neighborhood connectivity is improved by approximately 32%.

“…In Reference 31, the CDF of the per‐hop SNR was used in this study to estimate the OP of the relay‐aided system for 5G, which is valid for all fading situations taking into account a dual‐hop DF relay system. A detailed analysis of the system performances in terms of OP and throughput over multipath Rayleigh fading channels is provided by the research in Reference 32.…”

One of the promising technologies for achieving virtual diversity gains is cooperative relaying. This study considers a dual‐hop dual‐branch cooperative diversity system with an amplify‐and‐forward mechanism where the hop count here means the total number of relays between source and destination which equals two. Utilizing the best‐path selection combining technique, a closed‐form formula for the average bit error rate and outage probability is obtained. Furthermore, between the nodes in the two branches, we consider independent non‐identical Nakagami‐m slow flat fading channels. The Monte Carlo simulation results are confirmed with the analytical ones.

“…To meet the increasingly demanding requirements, fifth-generation networks have emerged, aiming to offer significantly higher performance than previous generations [2,3]. Among the performance criteria of these networks, the signal outage probability is a key factor [4,5]. In 5G mobile networks, multiple access techniques have been proposed [6,7] to optimize their performance compared to 4G networks.…”

In this article, we evaluate the impact of a new successive interference cancellation scheme on the signal outage probability in the context of PD-NOMA (Power Domain Non-Orthogonal Multiple Access) transmissions. The outage probabilities were assessed for 2 users, UE1 (closest to the base station), and UE2 (farthest from the base station), in a Rayleigh fading channel. The conducted simulations enable a comparison of signal outage probabilities for mobiles using a proposed successive interference cancellation (SIC) decoding scheme, where all interferences with other signals are cancelled, and a standard successive interference cancellation scheme, where only interferences from stronger signals are cancelled. Our simulations establish that the proposed SIC decoding model improves the outage probability performance by 25% for the user farthest from the base station. Generally, an improvement is observed for all mobiles in the network except for the strongest user closest to the base station. In fact, the performance of both SIC decoding models remains identical for the specific case of the strongest user.
