Optimization of power saving and Latency in LTE network using DRX mechanism

The revolution and advancement in communication field necessitates the user equipment (UE) to have least power consumption, reduced latency, enhanced life time and better QoS. Discontinuous reception mechanism (DRX) is a methodology proposed in Long Term evolution (LTE) networks to accomplish the preferred effect. Although DRX mechanism introduces latency in the system, the power that can be saved in an active and background traffic is comparatively good and enhances the life time of the UE. This article focuses on power saving up to 90% in UE and latency being introduced in the process. Furthermore, trading-off the DRX parameters can result in optimization of latency and power. Thereby, better quality of service and enhanced lifetime of the UE can be achieved.
