Venue Cast User Prioritized Round Robin Scheduling Algorithm

Abstract

The demand for video services such as live video streaming, video on demand etc., over mobile broadband has been growing rapidly in recent years and is expected to increase in near future. If the mobile networks consider unicast transmissions to every user accessing live video streaming applications then it may lead to inefficient resource utilization and reduced fairness among users. In order to support these high data rate video service users, Long Term Evolution (LTE) network has adopted mobile broadcasting and multicast mechanism for efficient utilization of the available spectrum. Mobile broadcasting is a mechanism that efficiently delivers same content using common resources to many users. The design of resource allocation strategies for broadcast and multicast services is required to achieve high performance in terms of both total service throughput achieved and fairness among all the users. Hence in this paper, Venue Cast User Prioritized Round Robin (VCUPRR) Scheduling Algorithm is proposed to enhance throughput and fairness of venue cast users accessing same venue specific content. The performance of proposed scheduling algorithm is evaluated using QualNet 7.1 network simulator by considering aggregate throughput, average delay and average jitter as performance metrics.
