Load Balancing Efficiency Improvement Using Hybrid Scheduling Algorithm in LTE Systems

Abstract

Long term evolution (LTE) is a recently evolving technology which ensures the reliable delivery of the heterogeneous traffic services with high speed data rate and lower delays through their mobile and other hand held devices. The key feature of LTE is its traffic engineering which is used for effectively managing the network resources for efficient utilization. When LTE expertise has arisen there are some prevailing problems to be taken care of i.e. load balancing and traffic scheduling. Even LTE is the debauched technology, but it is also been anguishing from these problems. In this paper, a load balancing strategy has been espoused that is based on traffic scheduling. Various Traffic scheduling algorithms are designed earlier to assign shared resources among users to optimize the performance of LTE systems in an efficient manner. The performance of three types of scheduling algorithms is compared in this paper namely first come first serve (FCFS), round robin (RR) and hybrid algorithm which is the combination of FCFS and RR in extremes conditions. The discussed scheduling algorithms performance is measured in terms of symbol error rate and signal to noise ratio.
