MANETs are dynamic peer-to-peer networks that use multi-hop data transfer without the need forpre-existing infrastructure. Due to their nature, for secure communication of mobile nodes, they need unique security requirements in MANET. In this work, a Hybrid Firefly Cyclic Rider Optimization (FCRO) algorithm is proposed for Cluster Head selection, it efficiently selects the cluster head and improves the network efficiency. The Ridge Regression Classification algorithm is presented in this work to detect the malicious nodes in the network and the data is transmitted using trusted Mobile nodes for the QoS performance metric improvement. A trust-based routing protocol is introduced using the Atom Emperor Penguin Optimization (AEPO) algorithm, it identifies the best-forwarded path to moderate the routing overhead problem in MANET. The proposed method is implemented using Matlab software and the performance metrics are packet delivers ratio, packet loss ratio, routing overhead, throughput, end-to-end delay, transmission delay, network lifetime, and energy consumption. The proposed AEPO algorithm is compared with the existing PSO-GA, TID-CMGR, and MFFA. The AEPO algorithm’s performance is approximately 1.5%, 3.2%, 2%, 3%, and 4% higher than the existing methods for packet delivers ratio, packet loss ratio, end-to-end delay, and throughput and network lifetime. This evaluation enables the sender nodes to improve their data transmission rates and minimizes the delay. Additionally, the suggested technique has a clear benefit in terms of demonstrating the genuine contribution of distinct nodes to trust evaluation.","PeriodicalId":330638,"journal":{"name":"WSEAS TRANSACTIONS ON COMMUNICATIONS","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126104976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Enhancing Congestion Control and QoS Scheduling Using Novel Rate Aware-Neuro-Fuzzy Algorithm in MANET","authors":"S. Mohan, DR. P. Vimala","doi":"10.37394/23204.2023.22.6","DOIUrl":"https://doi.org/10.37394/23204.2023.22.6","url":null,"abstract":"Mobile Ad Hoc Networks (MANET) provides a vibrant atmosphere wherein data may be substituted deprived of the necessity of human authority or a centralized server, as long as nodes work together for routing. As long as security throughout the multipath routing protocol and data transfer over many routes in a MANET is a difficult problem, this work offers a message security technique. This study presents the congestion control and QoS scheduling mechanism. The goal of this study is to examine standardized MAC protocols on MANET, to measure performance under various node densities and MAC protocols. Initially, this work presents the Centralized Congestion Detection method to detect congestion with baseline parameters. Accordingly, the congestion is avoided using Novel Rate Aware-Neuro-Fuzzy based Congestion Controlling strategy. This method effectively controls the congestion in the Network. This mechanism has been proposed which defines three levels of congestion based on which the data rate, throughput, overhead and delay. However, after controlling the congestion, the optimal routes are given to the packets by proposing an Ambient Intelligence-based Ant colony optimization quality-aware energy routing protocol (AIACOAR). This method finds the most efficient route to a destination and decreases the time and energy required. Accordingly, for securing the network against malicious attacks, an Elliptic Curve Cryptography (ECC) encryption mechanism is presented. Consequently, the multihop scheduler performs QoS-based scheduling in MANET. Schedulers in MANET take into account various QoS parameters such as end-to-end packet delay, packet delivery ratio, flow priority, etc. The proposed method is implemented using Matlab software, and the evaluation metrics are PDR, jitter, congestion detection time, delay, route selection time, and throughput. The performance of the proposed method is compared to the existing AIFSORP and LF-SSO techniques. While compared to these methods, the proposed method’s performance is improved in terms of PDR, delay, throughput, etc. The PDR value of the proposed method reaches approximately 99%, and it produces a very low delay. This produces reliable route discovery, optimized congestion control, and better QoS scheduling, therefore, these improve the system performance. In future, a recent bio-inspired technique is presented to even more minimize energy consumption and further improve the system's performance.","PeriodicalId":330638,"journal":{"name":"WSEAS TRANSACTIONS ON COMMUNICATIONS","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132820021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New technologies are being born and some of them are taking so much importance in people’s lives. In a situation where people’s needs are getting more complicated and everybody’s lifestyle is advancing to another level, bigger and better infrastructure is needed. Managing all this process can’t be anymore a step by step process. It is strictly needed to evolve in automated process. Network configuration and reconfiguration may be a repetitive process, time consuming, and error prone process. To address this problem this paper is going to shed light on the benefits of an automated configuration and topology verification process. To this end, a proof of concept system, Netmiko, has been used in a case study. Netmiko scripts are able to read the current network state, can apply predefined configurations loaded from text-files or csv files, and automatically verify the network state. The goals of this paper are to demonstrate the development of Netmiko scripts, to illustrate the simplicity in the implementation, to compare the automated network system reconfiguration to a fully manual one, and, finally, to discuss potential pros and cons in switching to an automated network configuration process in everyday practice. A simple Packet Tracer simulation in joint with a GNS3 simulation are involved to evaluate this proof of concept. In Packet tracer a manual network configuration is performed while in GNS3 an automated network configuration is developed.","PeriodicalId":330638,"journal":{"name":"WSEAS TRANSACTIONS ON COMMUNICATIONS","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124152578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we look at existing wireless communication technologies in light of environment-aware wireless communications, which is a new concept of wireless communications that queries the time-invariant CSI from the local or global database, using information about the transmitter and receiver location. Thus, this study is the first critical review of the potential of today’s terrestrial wireless communication systems including wireless cellular technologies (GSM, UMTS, LTE, NR), wireless local area networks (WLANs), and wireless sensor networks (WSNs), for estimating CSI, the ratio between training and information symbols and the rate of channel variation, and the potential use of time invariable CSI in environment aware wireless communications. The research reveals, that early communication systems provide means for narrowband channel estimation and the CSI is only available as channel attenuation based on signal level measurements. By increasing the frequency bandwidth of communications, the CSI is estimated in some form of channel impulse response (CIR) in almost all currently used radio technologies, but this information is generally not available outside the communication systems. Also, the CSI is estimated only for the channel with active communications. The new radio technology (NR) offers the possibility of estimating the CIR for non-active channels as well, and thus the possibility of initiating environmentally aware wireless communications.","PeriodicalId":330638,"journal":{"name":"WSEAS TRANSACTIONS ON COMMUNICATIONS","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122091868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
