Abstract


The IEEE802.16e is the latest standard of the next generation of mobile wireless broadband metropolitan area to support the user node moves to the vehicle speed . In order to improve the energy efficiency of the mobile terminal , IEEE802.16e proposed three hibernation mode , wherein the energy-saving type I is used for best-effort BE traffic and non - real time variable rate NRT-VR business . In this paper, the energy-saving type I Sleep Research and Performance Analysis . First , based on the energy-saving type I sleep policy , respectively, consider the aftereffect business with self-similar traffic to establish the vacation length index change Geom/G/1 and GeomĪ¾/G/1 queuing model , given the rate of energy saving , energy consumption rate , the system switching rate and average data frame in response to the expression of the time and other performance indicators . Combination of numerical examples and system simulation , quantitative analysis of the impact of the the dormant window size on system performance . Second , considering the energy saving rate , the rate of energy consumption , the system switching rate and average data frame response time and system performance indicators , constructed cost function given hibernation the optimization settings window program . Given process based on switching between the sleep state and the wake-up state , the start threshold of the sleep policy . Then, in the basic energy-saving type I proposed a Sleep delay strategy . Parallel to the basic sleep policy , the establishment of expression with a the vacation delay , , vacation length index change Geom/G/1 and GeomĪ¾/G/1 queuing model , and given the relevant performance indicators . System simulation by numerical examples , quantitative analysis of the sleep delay timer on the system performance and verify Sleep postponement strategy effectiveness . Finally, for the energy saving type I with sleep delay , considering that the energy saving rate and data frames to the average response time compromise , structural cost function given hibernation delay timer size optimization setup scheme .
