【摘要】：经济的飞速发展伴随而来的是大量的能源消耗,这成为经济发展的巨大的成本和自然保护的极大挑战。互联网/通信行业和电能息息相关,也使得能耗问题甚至成为本行业发展的主要限制,因此解决能耗问题逐渐成为本行业研究的一大热点。目前较为常用的解决办法包括动态适应路由、网络拓扑优化等,但各种办法中休眠机制依然是控制能量消耗和浪费最切实有效的方法。尽管无线网络的各种休眠技术已相当成熟,但将之应用到未来网络的具体方案还有待研究。由于未来网络存在的网络节点分散、连接性差、时延长的特点,如何将休眠机制应用于未来网络成为一项较为困难的课题。本文以对等网路和延迟/中断容许网络这两种未来网络结构为例,对应用于其的两种休眠机制进行了研究与分析。基于对等网络,本文研究了一种绿色比特流协议,即在原有的标准比特流协议的基础上稍作改动,增加了休眠-唤醒事件,并修改其它事件的部分功能。对于该绿色比特流协议的性能评估,本文仿真了一个由50个节点组成的分蜂网络,结果显示,绿色比特流在几乎不牺牲文件下载时间的同时获得了至少75%的能量节约。对于延迟/中断容许网络,由于网络拓扑多变和网络间歇性的特点,本文研究了一种情境感知能量管理机制,即以异步休眠方式为基础,讨论各项休眠参数值如何选定,才能在保证邻居发现、缩短时延、增加可靠性的同时最大化能量节省。本文给出了选取休眠参数值的指导参考,该指导为网络设计人员在DTN网络中增加休眠机制提供了理论依据。仿真实验模拟了不同网络密度、通信负载、节点速率和休眠模式下本机制的运行情况。最终得出结论,该情境感知能量管理机制的使用,可以使得延迟/中断容许网络在几乎不损失传输速率和平均时延的基础上节省约80%的电量。
[Abstract]:The rapid development of economy is accompanied by a large amount of energy consumption, which has become a huge cost of economic development and a great challenge to nature conservation. The problem of energy consumption has even become the main limitation of the development of the industry, so solving the problem of energy consumption has gradually become a hot spot in the industry. At present, the more commonly used solutions include dynamic adaptive routing. Network topology optimization and so on, but the sleep mechanism is still the most effective way to control energy consumption and waste. However, the specific scheme to be applied to the future network is still to be studied. Due to the characteristics of the network node dispersion, poor connectivity and time extension in the future network. How to apply the dormancy mechanism to the future network becomes a difficult problem. In this paper, we take the P2P network and the delay / interrupt allowable network as examples. Based on peer-to-peer network, a green bitstream protocol is studied, which is based on the original standard bitstream protocol. The hibernation-wake-up event is added, and some functions of other events are modified. For the performance evaluation of the green bitstream protocol, we simulate a 50-node split bee network, and the results show that. Green bitstreams achieve at least 75% energy savings at least without sacrificing file download time. For delay / interrupt tolerance networks due to network topology variability and network intermittency. In this paper, we study a situation-aware energy management mechanism, which is based on the asynchronous sleep mode, and discusses how to select the parameters of sleep so as to ensure the neighbor discovery and shorten the delay. At the same time, the reliability is increased and the energy saving is maximized. This paper gives the guidance reference to select the sleep parameter value. The guidance provides a theoretical basis for network designers to add sleep mechanism in DTN networks. Simulation experiments simulate different network density and communication load. The performance of this mechanism under the node rate and dormancy mode. Finally, the conclusion is drawn that the use of the situation-aware energy management mechanism. The delay / interrupt tolerance network can save about 80% power on the basis of little loss of transmission rate and average delay.
