Improvement and performance analysis of a power-saving mechanism considering traffic patterns

Power saving is a salient issue regarding the 4G LTE network. In wireless networks, the frequent checking of the usage of the user equipment may lead to excessive power consumption, and the discontinuous reception mechanism of the LTE is implemented to avoid such excess. The DRX trade-off metrics between power saving and the delay constraint are investigated here for an improvement in the performance. In order to meet the UE QoS, this paper suggests a predictive mechanism with a delay constraint for the traffic patterns. The results for various traffic patterns show that the suggested mechanism offers beneficial power-saving effects while satisfying the UE QoS.
