Therefore, a malicious node can attack the network by continuously broadcasting RREQ packets at high frequency, which is called the RREQ packet flooding attack. The result is a broadcast storm that greatly increases media waste and resource waste. This article proposes a Flooding Attack Detection Mechanism Using the Median (FDMM) value to detect and prevent flooding attacks. Each node that installs the FDMM solution will collect the route discovery behavior history (V) of each node to construct the route discovery frequency vector; By calculating the median value (m) of V, the node compares the m value with a Fixed Threshold (FT) node that can identify a node that has performed malicious or normal behavior. The paper also proposes the Flooding Attacks Prevention and Detection Routing Protocol (FDMM AODV) protocol by improving the route discovery mechanism of the AODV protocol using FDMM. Simulation results show that our solution can detect over 98% of malicious nodes; Packet delivery ratio, routing load, and end-to-end delay are effectively improved.","PeriodicalId":53518,"journal":{"name":"Journal of Communications","volume":"59 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141696174","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}

International Civil Aviation Organization (ICAO) proposes using the L-Band Digital Aeronautical Communication System (LDACS) to meet future demands, but its implementation faces legal and interference challenges with existing L-band systems like Joint Tactical Information Distribution System (JTIDS), Military Tactical Air Navigation (TACAN), and Distance Measurement Equipment (DME). To address this, we propose employing Non-Orthogonal Multiple Access (NOMA) in Very High Frequency (VHF) digital systems, aiming to boost capacity without introducing new bands. Our study focuses on maximizing spectral efficiency using NOMA-based massive Multi-Input Multi-Output (mMIMO) for aeronautical communications. We evaluate different pairing algorithms (Gale Shapley, Hungarian, and correlation-based) and beamforming techniques Zero Forcing and Maximum Ratio (ZF and MR), finding that GS pairing with ZF beamforming yields the optimal solution. Results show that all three algorithms outperform fixed pairing NOMA, with GS being the least complex, followed by Hungarian and correlation-based. Additionally, ZF beamforming outperforms MR in achieving spectral efficiency. This integrated approach offers a promising strategy for enhancing aeronautical communication systems amidst growing air traffic demands.","PeriodicalId":53518,"journal":{"name":"Journal of Communications","volume":"39 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141695374","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}

Many protocols were addressed to solve the issues which were not able to give the permanent solution and still the Hidden Exposed nodes issue remains in the Mobile Adhoc Network. This article proposed the novel algorithm with the maintenance of Hidden and Exposed Table formation and Mutual Exclusion Request to Transmit (MERT), Mutual Exclusion Release (MER) signal to support the MAC (Medium Access Control) layer. Every node maintains the Hidden and exposed table using the Mutual Exclusion Medium access algorithm in each beacon signal. When a node wants to transmit a packet to another node, it finds the hidden and exposed nodes from the hidden and exposed table, and sends a Mutual Exclusion Request signal to all of the hidden and exposed nodes, instructing them not to transmit the packet until the Mutual Exclusion Release is received. The proposed work named as ME-Mutual Exclusion, Medium Access Control (MAC) protocol were implemented with the NS2.34 and results are compared with the traditional Nullifying Medium Access Control (NULLMAC) protocol, Receiver Dual Busy Tone Multiple Access (RDBTMA) protocol, WiCCP protocol WiMARK protocol, CAD-CW protocol, Contention-Free cooperative - Medium Access Protocol (CFC-MAC) protocol moreover the result achieves the proposed work attain the maximum Packet Delivery Ratio of 60%, less End to end Delay from 0 to 75ms and better Throughput.","PeriodicalId":53518,"journal":{"name":"Journal of Communications","volume":"18 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141698816","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}

To quantify the delay brought on by the abnormalities in the tropospheric layer, researchers have employed a variety of methods. Since Global Positioning System Radio Occultation (GPS-RO) systems and the Global Positioning System (GPS) ground network estimate the tropospheric delay differently, we examined this measurement difference in this study. Therefore, this study has been performed to analyze the dry delay measurement from the ground-based station and validate it with the reprocessing data from the space-based station to understand the correlation of measurement between these two methods. The MetopA gave the worldwide delay data, while the 92 SuomiNet Network GPS stations, which cover the majority of the United States region, provided their measurement of the delay utilizing the element of slant water along the GPS ray while the MetopA provided the global data with around 150 selected data per day and analysis was conducted for the data in the year 2020. Hence, due to the difference in spatial data distribution between these two types of data, the mean value has been measured for each of the latitude zones, the result shows the minimum bias of 0.67 cm and RMSE 4.51 cm at the − 30⁰ to − 60⁰ and the maximum bias of 3.74 cm and RMSE 25.1 cm at the 30⁰ to 60⁰ latitude. Overall bias and Root Mean Square Error ( RMSE) are 1.41 cm and 23.2 cm respectively which shows a good agreement between space-based and ground-based measurement that will help for better error modeling development in the future.","PeriodicalId":53518,"journal":{"name":"Journal of Communications","volume":"68 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141714780","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}
