The rise of 5G technology has increased the demand for in-flight services, challenging aviation communication to provide reliable data through satellite systems and traditional macro-cellular networks. However, airborne communication’s dynamic nature poses significant challenges, including irregular connections and variable delays. To tackle these challenges, a novel Smart Prediction and trAnsmission mechanism for delay taRgeted networK (SPARK) technique has been proposed to enhance the efficiency and reliability of DTNs in aviation communication. The proposed SPARK method includes a comprehensive node trust evaluation system, utilizing direct and indirect trust metrics to ensure network reliability. After evaluating node trustworthiness, the proposed method restricts heavy load traffic based on trustworthiness. The Prediction and Transmission Module incorporates the Cooperative Watchdog System (CWS) to dynamically update each node’s reputation score. Nodes are classified into cooperative, partially cooperative, neutral, mislead, and selfish nodes. Experimental results demonstrate the effectiveness of the suggested SPARK framework utilizing evaluation parameters including delivery rate, delay, overhead, hop count, throughput, complexity, and resource utilization. The delay rate of the proposed SPARK method is 18.67%, 19.87%, and 14.45% is lower than the existing OPRNET, IDRL, and CCMA, techniques respectively. The distribution of the proposed SPARK framework attains a forwarding rate of 11% for selfish, and 9.2% for misleading based on their packet forwarding behaviorOmrežje z zamikom (DTN) olajšuje komunikacijo v okoljih z naključno povezljivostjo in dolgimi zamiki, kot so vesoljske misije in izolirane lokacije. Razvoj tehnologije 5G je povečal povpraševanje po storitvah med letom, kar predstavlja izziv za letalsko komunikacijo, da zagotovi zanesljive podatke prek satelitskih sistemov in tradicionalnih makrocelularnih omrežij. Vendar pa dinamična narava letalske komunikacije predstavlja pomembne izzive, vključno z nepravilnimi povezavami in spremenljivimi zamiki. Za reševanje teh izzivov je bila predlagana nova tehnika Smart Prediction and trAnsmission mechanism for delay taRgeted networK (SPARK), ki izboljšuje učinkovitost in zanesljivost DTN v letalski komunikaciji. Predlagana metoda SPARK vključuje celovit sistem ocenjevanja zaupanja vozlišč, ki uporablja neposredne in posredne metrike zaupanja za zagotavljanje zanesljivosti omrežja. Po oceni zanesljivosti vozlišč predlagana metoda omeji promet z veliko obremenitvijo na podlagi zanesljivosti. Modul za napovedovanje in prenos vključuje sistem Cooperative Watchdog System (CWS) za dinamično posodabljanje ocene ugleda vsakega vozlišča. Vozlišča so razvrščena v sodelujoča, delno sodelujoča, nevtralna, zavajajoča in sebična vozlišča. Rezultati poskusov dokazujejo učinkovitost predlaganega okvira SPARK, ki uporablja parametre ocenjevanja, vključno s hitrostjo dostave, zamudo, režijskimi stroški, številom skokov, prepustnostjo, kompleksnostjo in izkoriščenostjo virov. Stopnja zamude predlagane metode SPARK je 18,67%, 19,87% in 14,45% nižja od obstoječih tehnik OPRNET, IDRL in CCMA. Porazdelitev predlaganega okvira SPARK doseže stopnjo posredovanja 11% za sebične in 9,2% za zavajajoče vozlišča na podlagi njihovega vedenja pri posredovanju paketovTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaStrokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale
