To solve this problem, based on the concept of graph theory we give a few models and arithmetic designs of virtual backbone in the environment of different application, and propose the corresponding routing mechanism with these virtual backbones. The major achievements are outlined as follows:The state of host's power or the time of host's online plays an important role in keeping stability of a virtual backbone. With a view to this feature, the paper introduces a simple and efficient heuristic algorithm for calculating the virtual backbone by seeking a minimum connected dominating set with maximal weight. The maximality of the weight-based choice of backbone nodes guarantees that the most suitable nodes have been chosen for the role of backbone nodes so that they can properly coordinate all the other nodes and keep stability of the virtual backbone in the network.

为了解决这个问题，本文利用网络图论中的一些理论，在不同的应用环境下给出几种虚拟骨干网的模型、构建及基于稳定性和节能的算法设计，并针对这些骨干网提出相应的分层路由机制，主要研究内容和贡献如下：考虑到主机的功率大小和在线时间长短对虚拟骨干中心的相对稳固性的影响，提出用基于极大权的最小连通支配集模拟虚拟骨干网；并给出其数学模型和相应的启发式算法，确保了性能强的主机担任骨干节点；通过优化规则确保骨干网的极小性，有效地减小了控制分组转发开销；最后进行了仿真验证。

The studies of McCarthyism in America have gone through three stages. From 1950s to the middle of 1970s is the starting stage. The prosperous stage which I called is from the middle of 1970s to 1990s. In this period, great achievements have been made and some relevant problems have been studied. After 1990s, though the passionate of the studies of McCarthyism has relatively passed, it is still a focus the scholars paid attention to.

美国史学界对麦卡锡主义的研究可分为三个阶段。20世纪50～70年代中期是起步阶段。20世纪70年代中期～90年代初期取得重大成果，相关问题的研究在这一时期展开，可以说是对麦卡锡主义研究的繁荣阶段；20世纪90年代以后对麦卡锡主义研究的热情相对减弱，但仍是学者们关注的焦点。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor".
