Performance analysis of LTE device using OTSC ratio for delay bound violated traffic

Advanced techniques of fourth generation (4G) Long Term Evolution (LTE) network provides high data rate with guaranteed Quality of Service (QoS) for real time applications like interactive gaming, High Definition (HD) video streamings and voice services. Maintaining the QoS in a delay bound violated traffic poses a challenging task. In this paper, the performance analysis on energy savings of User Equipment (UE) in LTE networks are made considering the discarded packets due to delay bound violation. In addition, an approach of On-Timer to Short Cycle (OTSC) ratio has been incorporated in the DRX mechanism to achieve better energy saving factor. The simulations are done using MATLAB. The simulation results depict that the better energy saving is achieved with appropriate configuration of DRX parameter with the OTSC ratio.

I. Introduction

The recent advances in wireless communication systems have deployed a new trend in the electronic market. Varieties of smart phones in the electronic market are highly capable of handling the high data rate multimedia services. The effective processing of multimedia data services by the 3rd Generation (3G) has not fulfilled the Quality of Service (QoS) due to higher latencies during transmission. To improve the QoS with minimal latency in transmission and with an acceptable service cost, new radio access technology called Long Term Evolution (LTE) is introduced by 3^rd Generation Partnership Project (3GPP). The LTE has characterized with potential capabilities to provide higher bandwidth, lower latency transmission, and higher throughput with acceptable QoS. The high speed data service support by LTE network has exponentially increased the demand of User Equipments (UE) in the electronic market. Moreover, the support of UE on Multi Player interactive gaming applications, High Definition (HD) video streaming, Online video Conferencing, Voice over Internet Protocol (VoIP) applications attract more users to utilize LTE network frequently.
