Research ArticleOpen accessIn the author namesDesign a New Bidirectional Transmission Protocol to Improve the Performance of MAC Layer Based on Very High Speed WLANsAli Ahmad Milad, Zul Azri Bin Muhamad Noh, Abdul Samad Shibghatullah et al.This paper presents a new bidirectional transmission protocol with single data frame to computing the performance of MAC layer based on IEEE 802.11n. As high as 600 Mbps of physical data rate is achieved in IEEE 802.11n where high data rate the current MAC layer leads to high performance overhead and low performance of throughput and designing the MAC layer … …Journal of Computer Science, Vol. 11, Issue 5 · 23 Jun 2015 · 6,952 accessesView PDFCite
Research ArticleOpen accessIn the author namesTRANSMISSION CONTROL PROTOCOL PERFORMANCE COMPARISON USING PIGGYBACK SCHEME IN WLANSAli Ahmad Milad, Zul Azri Bin Muhamad Noh, Abdul Samad Shibghatullah et al.The main problem at wireless networks is the overhead at MAC layer; when the data physical rate is increasing it causes increasing the overhead and decreasing at the MAC efficiency. In this study we study the performance comparison of TCP protocol in WLANs with and without using piggyback. The study of results concerning of implemented both mechanisms in NS2 simulator … …Journal of Computer Science, Vol. 9, Issue 8 · 2 Jul 2013 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the author namesComparative Study of Performance in Cryptography Algorithms (Blowfish and Skipjack)Ali Ahmad Milad, Hjh Zaiton Muda, Zul Azri Bin Muhamad Noh, Mustafa Almahdi AlgaetProblem statement: The main goal guiding the design of any encryption algorithm needs to be secured against unauthorized attacks. For all applied applications, performance and the cost of implementations are also important concerns. A data encryption algorithm would not be of much use if it is secure enough but slow in performance because it is a common repetition to embed … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jul 2012 · 8,021 accessesView PDFCite
Review ArticleOpen accessIn the abstractEfficiency and Sustainability of Alternative Protein Sources for Livestock Production in Sub-Saharan Africa: A Systematic Review and Meta-AnalysisOlusegun Oyebade Ikusika, Bulo Luvuyo, Jaja Ishmeal FestusSub-Saharan Africa (SSA) faces growing challenges in sustainable livestock production due to high costs and limited availability of conventional protein sources such as soybean meal and fishmeal. This systematic review and meta-analysis evaluated the nutritional efficiency and sustainability of locally available alternative protein sources for livestock feed in SSA. Following PRISMA guidelines, systematic searches were conducted across five databases (PubMed, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 19 Feb 2026 · 1,849 accessesView PDFCite
Research ArticleOpen accessIn the abstractVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecies Assemblages and Distribution of Dinoflagellate Cysts from three Estuaries Sediment’s of Makassar Strait, Eastern IndonesiaNita Rukminasari, Akbar TahirMakassar Strait encompasses high fisheries resources and high biodiversity and primary productivity. Algae blooms often occur in these areas, but there is a lack of studies that have been carried out on HABs in these locations specifically determining the collection and abundance of dinocyst. The study aimed to determine species assemblages of dinoflagellate cysts from three estuaries of Makassar Strait. … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 8 May 2021 · 6,327 accessesView PDFCite
