Item SETTING QoS Wi-Fi PARAMETERS FOR THE SUDAN(Neelain University, 2018) Diaeldin Awad Abdelrahman ElgamelAbstract Sudan telecom market has no existing parameters for WiFi QoS parameters The main objective of this research is to set four QoS WiFi parameters (delay, retransmission attempts, jitter and throughput) to overcome the complete absence of such parameters for QoS WiFi in Sudan, Wifi QoS parameters has to be considered as an important factor for the wireless technology, hence they should be organized and controlled to meet the end users quality of service (QoS) perceptions . Difficulties and challenges face the research, as a few countries have their QoS WiFi parameters. Number of related experiences on the topic handled by author was addressed and analyzed, which were taken as references for the research as a bench mark. Simulation software Opnet 17.5 has been fed with the experimental inputs, and was used to generate the parameters by feeding the simulation with the adequate inputs. Many published research were addressed to compare the simulation results with. Simulations resulted parameter, addressed, analyzed and discussed. Many recommendations were proposed, from which the regulator was asked to consider these parameters as a pilot scheme and could be mandated to WiFi providers in Sudan market, recommendation for enhancement and generating annual reports was upraised. The metric parameters values obtained were compared with the references results. The final output metric parameters, has been recommended as pilot values for the four addressed parameters. A completion of the remaining QoS WiFi parameters by authority or researchers is highly recommended. المستخلص سوق الإتصالات بالسودان لا توجد به بارمترات لجودة خدمات الواي فاي . من أهم أهداف هذا البحث إيجاد قيم رقمية لأربعة من بارامترات جودة خدمات الواي فاي وهى:- (تأخر وصول البيانات ,عدد محاولات إعادة الإرسال ,التغير الحادث من تأخير وصول البيانات ,النفاذية ). تعتبر بارميترات جودة خدمات الواي فاي من أهم عناصر التكنلوجيا اللاسلكية ,وعليه لابد من تنظيمهم والتحكم بهم لمقابلة إحتياجات المشتركين . لقد واجه البحث بعض الصعوبات لقلة عدد الدول التي وضعت بارميترات لجودة خدمات الواي فاي . وقد تناول البحث عدد من الأوراق ذات العلاقة بموضوع البحث وتم إخضاعها للدراسة واتخذت بعض الأبحاث كمراجع البحث . تم إستخدام المحاكي أوبنت (17,5) في هذا البحث لإستخراج النتائج وفد تمت مقارنتها بالأبحاث المنشورة كمراجع للنتائج .
