1 Performance of Power Efficient Wake-Up Mechanisms for Mobile Multimedia Communication with Bursty Traffic

Abstract:- The mobile communication handset system can be divided into three units of consuming battery power, which are data receiving, data processing, and the user interface units. Among other things, one of the power-efficient mechanisms is to make the data processing and the user interface units stay on the sleep state while the data receiving unit is waiting for packets from wireless network. We study two wake-up schemes: the threshold and the vacation schemes to conserve power. To take account of traffic burstiness, we consider three traffic models: the Poisson Process, the Interrupted Poisson Process (IPP), and the 2-state Markov Modulated Poisson Process (MMPP). Analytical models are considered to evaluate two wake-up schemes under three different traffic models. The performance measures of interest are the switch-on rate, the packet dropping probability, and the waiting time
