摘要：

分析了MOST网络的传输原理和特性,根据网络的管理和通知机制,设计了从节点自主休眠和主节点管理整体网络休眠的分布式电源管理方案,以及睡眠状态下节点和网络的唤醒机制,并利用MATLAB对网络功耗进行数学建模和分析。仿真中MOST网络在执行随机生成的相同任务序列后,基于分布式电源管理的网络系统总功耗小于原来超时策略下的系统总功耗,仿真证明了分布式电源管理策略的有效性。

关键词: 电源管理, 多媒体系统传输(MOST), 通知机制, 分布式系统

Abstract:

The transmission principle and characteristics of MOST(Media oriented systems transport) networks were analyzed.Depending on the network management and the notification mechanism,a distributed power management solutions was designed that the slave nodes can sleep independently and the master node manages the network state,and the wake-up mechanisms in the sleep state were proposed.A mathematical modeling and analysis of MOST networks power were built in MATLAB.After executing the same sequence of tasks generated randomly,the total cost of MOST based on a distributed power management is always less than the total cost of MOST based on a timeout policy.Simulation results show that the distributed power management strategy is effectiveness.

Key words: power management, media oriented systems transport(MOST), notification, distributed system
