Evaluation Packet Priority Mechanisms over 5G Mobile Network

Abstract

In wireless networks, enhancing the Quality of Service (QoS) is main purpose of mobile providers. In real-time applications like video monitoring, Mobile networks transport various forms of packet traffic. These applications should have the gain of QoS acclimation. In order to guarantee QoS of mobile networks several Packet Priority Mechanisms (PPMs) are employed at the router. IoT devices are expected to rise considerably over mobile networks 5G a consequence of increasing the capacity and high data rates. These mobile networks face some issues in overload and congestion in Radio Access Network (RAN) because of the massive IoT device packet traffic requiring various levels of QoS requirements. In this article, the method PPMs namely, First-In-First-Out (FIFO), Priority Queuing (PQ), and Weighted Fair Queuing (WFQ) in 5G and 4G networks taking into consideration QoS requirements in IoT and smart systems scenarios are investigated and compared. The three evaluated PPMs were designed over 4G and 5G mobile networks in terms of the user's suitability to enhance the priority order. The results of the OPNET simulation show that the performance evaluation allowed us to draw conclusions on the performance of the three-PPMs and point out the strengths and weaknesses.
