dc.description.abstract	The Third Generation Partnership Project (3GPP) has recognized machine-type communications (MTCs) as a vital medium to drive the Internet of Things (IoT). One of the key challenges in MTC is to reduce the energy consumption of the MTC user equipment (UE). Currently, the 3GPP Long Term Evolution (LTE)/LTE-advanced (LTE-A) standards incorporate discontinuous reception (DRX) mechanism for this purpose and the 3GPP extends the length of a DRX cycle. Therefore, how to configure the extended DRX (eDRX) cycle is a tradeoff between the delay in each session and the paging waste for a user equipment with a velocity, i.e. the extra cost of finding a user. In this paper, we analyze the tradeoffs and determine the optimal length for the eDRX cycle. The objective function is to minimize the total battery usage considering the tradeoff with the delays and the paging wastage. The analytical and simulation results demonstrate that the proposed mathematical model can mitigate the paging wastage and delay for the networks and the battery consumption of the user equipment.	en_US
