Harmonizing Mechanism for Power Saving and Delay Reduction in LTE Networks using DRX

P. Arunagiri, G. Nagarajan


The need of User Equipment (UE) has been increasing day by day. This has henceforth necessitated the need for the investigation of the power consumed in the user equipment during switching process and to come up with a method to reduce the power loss that occurs in the system. This is achieved using Discontinuous Reception Mechanism (DRX).DRX is a methodology proposed in Long Term evolution-LTE networks to achieve more power saving. DRX mechanism also has the tendency to introduce latency in the system. Using the DRX mechanism the power that can be saved in active and background traffic is comparatively good. This paper focuses on optimizing power saving in UE and to reduce latency introduced in the process. By properly scheduling the DRX parameters, an optimized output with proper power saving and less latency can be obtained. Results show that, a better quality and lifetime of user equipment can be obtained.
