New Scheduling Algorithm Proposed for Real Time Traffic Over LTE Femto-Cell

Abstract

Due to the inadequate indoor signal penetration, the indoor environment coverage becomes poor, which diminishes the quality of voice and video applications and slows down high-speed data services, which leads to customer churn, who expect high quality of service. To keep customers satisfied, Long Term Evolution (LTE) has developed a new advanced technology called FemtoCell, conceived to boost cellular network performance and is achieved with the use of access points installed by home users. The purpose of this paper is to analyze the performance of new proposed algorithm for voice and video over LTE FemtoCell, and to compare its performances with some well-known algorithms such as the proportional fair algorithm (PF), Exponential Proportional Fairness (EXP/PF), Logarithm Rule (LOG-Rule), Exponential Rule (EXP-Rule) and Modified Largest Weighted Delay First (MLWDF), The performance evaluation is conducted in terms of system throughput, delay, and Packet Loss Ratio. Finally it will be concluded that the proposed scheduler satisfies the quality of service (QoS) requirements of the real-time traffic in terms of packet loss ratio (PLR), average throughput and packet delay. This paper also discusses the key issues of scheduling algorithms to be considered in future traffic requirements.
