As smartphones have become increasingly pervasive, large amount of mobile data traffic has started to overwhelm the networks. Surprisingly, according to [1], the main cause of network congestion in cellular networks today is not only the data traffic generated by smartphones, but also the underlying signaling from the smartphone applications such as push email, instant messaging, and social network...
We analyze a sleep mode operation in IEEE 802.16m mobile WiMAX. We construct a 3-dimensional embedded Markov chain for the sleep mode with both uplink and downlink Poisson packet arrivals. We obtain the average power consumption and the average packet delay. The analytical results match with simulations very well. Performance evaluations show that there is a trade-off between the power consumption...
We mathematically analyze a sleep mode operation proposed by Samsung for IEEE 802.16 m. The sleep mode operation for downlink traffic is modeled as a 2-dimensional Markov chain. We obtain the power consumption of a mobile station. We show that the power consumption of a mobile station decreases as the sleep cycle increases and the analytical results also match with the simulation results very well.
