提出了一种带宽与能量等资源受限网络(如移动自组织网MANET)灵活机动能力的评估框架。当前已提出了一些有关网络灵活性与防御策略的新方法,但是在确保任务成功的前提下,评估这种策略代价与效用的框架却十分缺乏。首先概括了评估的基本要素,如任务目标、操作环境与机动类型;接着介绍了用于度量网络健康、安全、性能及其相互关系的有关概念测度与基本框架设计。分别在存在和不存在入侵检测条件下,给出了在一定时间确保关键通信路径安全的简单网络防护操作,以说明在基于该框架的要素与目标任务选择网络机动方式时,需要考虑的事项。
A framework for assessing the mobility of resources such as bandwidth and energy, such as MANET, is proposed. A number of new approaches to network resiliency and defense strategies have been proposed so far, but the framework for assessing the costs and utility of such strategies is scarce in ensuring the success of the mission. First of all, the basic elements of assessment are summarized, such as mission objectives, operating environment and mobility types. Then, the concept measurement and basic framework design for measuring network health, safety, performance and their relationship are introduced. In the presence and absence of intrusion detection, a simple network protection operation is proposed to ensure the safety of the critical communication path at a certain time, so as to illustrate the issues to be considered in choosing the network maneuver based on the elements of the framework and the target task.
