WSN nodes often operate on limited battery capacity, so energy efficiency is a significant problem for clustering and routing. In addition to these limitations, one of the primary issues of WSNs is achieving reliability and security of transmitted data in vulnerable environments to prevent malicious node attacks. This work aims to develop a secure and energy-efficient routing protocol for fault data prediction to enhance WSNs network lifespan and data reliability. The proposed technique has three major phases: cluster construction, optimal route selection, and intrusion detection. The adaptive shark smell optimization (ASSO) technique was initially used with three input parameters for CH selection. These parameters are the residual energy, the distance to the BS, and the node density. After clustering, salp swarm optimization (SSO) is used to select the optimum path for data transmission between clusters, resulting in an energy-efficient WSN. Finally, to ensure the security of cluster-based WSNs, an effective intrusion detection system based on a modified Elman recurrent neural network (MERNN) is implemented to detect the presence of intrusions in the network. The experimental results show that it outperforms the competing methods in various performance metrics. The performance results of quality of service (QoS) parameters are expressed as dispersion value (0.8072), packet delivery rate (98%), average delay (160 ms), network lifetime (3200 rounds), and the accuracy of this method is 99.2%. Compared to the SVM, ELM, HMM, and MK-ELM protocols, the proposed protocol increases network lifetime by 77%, 60%, 45.4%, and 14.2%, respectively.</p>","PeriodicalId":51194,"journal":{"name":"Telecommunication Systems","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When separating multiple source signals, the performance will deteriorate sharply. Since the existing methods of this kind use only a single algorithm for virtual channel expansion, they cannot retain all the source signals’ valuable information and effectively separate the multiple source signals. From the perspective of making the constructed virtual multi-channel signal contain enough information of the source signals as much as possible, this paper proposes a SCBSS algorithm based on improved wavelet packet and variational mode decomposition (IWP-VMD-SCBSS). Firstly, the source number is estimated according to the interval sampling method and the minimum description length (MDL) criterion. Secondly, the signal reconstruction method based on improved wavelet packet decomposition (IWPD) is used to reconstruct multiple purer virtual signals. Then the virtual signals are combined with the first intrinsic mode function (IMF) of two-level variational mode decomposition (VMD) and the original single-channel observed signal to constitute a virtual multi-channel signal. Finally, the joint approximate diagonalization of eigen-matrices (JADE) algorithm is used to process the virtual multi-channel observed signal to achieve BSS and obtain estimated source signals. The simulation results indicate that the IWP-VMD-SCBSS algorithm can achieve a lower symbol error rate (SER) than existing algorithms and lower computational complexity. It can solve the SCBSS problem of multiple communication signals effectively under an unknown source number.</p>","PeriodicalId":51194,"journal":{"name":"Telecommunication Systems","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140129865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, RLNC often suffers from high coefficients overhead, specifically, when it’s applied to limited resource or short-packet networks. Herein, the problem of RLNC coefficients vector overhead is revisited. A novel framework, based on modular arithmetic and prime numbers, and influenced by the Chinese remainder theorem (CRT), is proposed to reduce the coefficients overhead by augmenting only a tiny one item coefficient instead of the entire coefficients vector. The proposed method successfully addresses all the shortcomings of previous methods, including restrictions on generation size and packet density, recoding on intermediate nodes, and creating innovative coding vectors.

Optical satellite communications have provided a solution to this problem, allowing to increase exponentially the transfer rate between the ground station and an in-orbit satellite. However, although this technology offers numerous advantages, such as higher bandwidth, lower power consumption, narrower beam width, as well as greater simplicity of development, when the transmitted light signal passes through the atmosphere it experiences attenuation and fluctuations due to atmospheric turbulence. In this work, optical power fluctuations are modelled by means of a Gamma-Gamma optical turbulence model, so strong turbulence conditions are established according to Rytov’s turbulence theory, considering a measure of the intensity of the optical turbulence when extended to strong fluctuation conditions, depending on the zenith angle variations from 0<span>(^circ )</span> to 60<span>(^circ )</span>. Finally, the performance evaluation of BPSK and OOK modulation schemes for conditions with variations of pointing angle, based on atmospheric attenuation, signal scattering and absorption is given. The results show better performance of the modulation schemes at low zenith pointing angles and wavelengths of 1550 nm, over 850 nm and 1064 nm.

We derive the coverage area gain (CAG) brought by deploying RIS to the whole system and analyze how the deployment parameters influence performance. The results reveal that it is more favorable to deploy the RIS close to the base station (BS) to gain more long-range coverage, and the coverage area gain can keep approximately constant as long as the ratio of the RIS element number to the deployment distance (between the BS and the RIS) remains unchanged. The scaling law between the CAG and the ratio is obtained. Furthermore, we extend the analysis to the scenario with two RISs deployed and respectively derive the coverage area gains brought by the two RISs when they are symmetrically and vertically deployed.

With the overall advancement of IPv6 Internet deployment, the changes in network structure and paths will generate different degrees of delay. In this context, a comparative analysis of the behavioral characteristics of IPv4 and IPv6 network delay was performed in this study. We selected the sampled data of valid paths located at four monitors on different continents under the CAIDA_Ark project to obtain statistics for the network delay and communication diameter on the IPv4 and IPv6 Internet and found that their correlation was extremely weak. Furthermore, the communication diameter on IPv6 Internet was slightly shorter than that on IPv4 Internet. The network delay exhibited a bimodal or multimodal heavy-tailed distribution. The network delay and maximum link delay for IPv4 and IPv6 Internet were strongly correlated, indicating that the bottleneck delay affects the relationship between the network delay and communication diameter. Next, we analyzed the relationship between network delay and bottleneck delay for IPv4 and IPv6 Internet and found that bottleneck delay has a more significant impact on the network delay on the valid paths for IPv4 Internet than for IPv6 Internet. After mapping the IP addresses at both ends of the bottleneck delay to the Autonomous Systems (ASes), we found that the bottleneck delay on the valid paths for the IPv4 Internet was mostly distributed in the intra-AS, whereas it was in the inter-AS for the IPv6 Internet. Finally, we analyzed the factors affecting bottleneck delay and found that propagation delay in the long-distance range is an important factor (<em>L</em> &gt; 4000 km on IPv4 Internet and <em>L</em> &gt; 7000 km on IPv6 Internet).
