In this paper, Discontinuous Reception, a power saving mechanism in Long Term Evolution wireless networks, is analytically investigated in the presence of transient faults by using an unreliable M/G/1 queue with multiple vacations. System failures may occur either due to transient faults in the mobile device or due to wireless link errors. When a failure occurs, the device may request the retransmission of the packet after a recovery period. In such a case, the power consumption will be further increased. Steady state analysis is presented, and decomposition results are discussed. Energy and performance metrics are obtained, and used to provide useful numerical results.
