Differentiated QoS with Modified C/I Based Scheduling Algorithm
A. Divya, Sanjay Singh

TL;DR
This paper proposes two modified radio resource management algorithms for 3G UMTS networks, enhancing QoS by prioritizing users and improving service for users in degraded conditions, validated through NS-2 simulations.
Contribution
Introduction of prioritized C/I and modified inverse C/I scheduling algorithms for better QoS in 3G networks, with performance evaluation via NS-2 simulations.
Findings
Prioritized C/I scheduling improves QoS for high-priority users.
Modified Inverse C/I scheduling enhances service for users in poor channel conditions.
Simulation results show significant QoS improvements over traditional algorithms.
Abstract
Second-generation (2G) digital cellular systems constitute the majority of cellular communication deployed today. A variety of services of 2G systems has increased significantly and this will continue to grow even further in the emerging third-generation (3G) systems. Universal Mobile Telecommunication System (UMTS) is a third-generation mobile communications system which uses the Wide-Band Code Division Multiple Access (WCDMA) technique to support a wide variety of services, like speech, video telephony, Internet browsing, etc. These services require a wide range of Quality of Service (QoS) requirements. QoS is an important issue as the number of multimedia services increases day by day. Differentiated QoS methods allow the differentiation of users based on their priority levels and channel conditions so that the network can allocate the bandwidth for a particular request based on the…
