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。

China's "Highway Engineering Technical Standards" will be divided into high-level road according to technical quality, sub-senior, middle and low-level four kinds, all kinds of road surface types are as follows: Senior Pavement - asphalt concrete pavement, cement concrete pavement, plant mix asphalt crushed stone pavement, stone pavement of rocks or neat; second high-level road surface - asphalt penetration-style pieces, gravel road, asphalt road debris, gravel road, asphalt road surface, Treatment, semi-neat stone pavement; middle road - broken, gravel (size distribution, or clay-bound) road surface, irregular stone pavement, other granular surface; low road - aggregates stabilized soil surface, and other local materials, reinforcement or improvement of soil surface.

中国《公路工程技术标准》将路面按技术品质分为高级、次高级、中级和低级四种，各种路面的面层类型如下：高级路面——沥青混凝土路面，水泥混凝土路面，厂拌沥青碎石路面，整齐石块或条石路面；次高级路面——沥青贯入式碎、砾石路面，路拌沥青碎、砾石路面，沥青表面处治路面，半整齐石块路面；中级路面——碎、砾石路面，不整齐石块路面，其他粒料路面；低级路面——粒料加固土路面，其他当地材料加固或改善土路面。

Can think that road traffic safe program is government and its function department is , make the personal casualties of road traffic accident lose with property in program issue fall to the goal intended, determine in the traffic safe measure and action and its enforcement that person, vehicle, road and environment should adopt with the aspects such as management sequential, it is different levels people's government and its function department science develop the road traffic at will sexual major basis and important means of blindness of working and preventing road traffic safely working decision safely , it is strategy and the direction of road traffic safe development, have the scientificness of guaranteeing road traffic safe management and avoid decision fault before Zhan sexual role, have important strategic meaning for preventing road traffic accident.

可以认为，道路交通安全规划是政府及其职能部门为使道路交通事故的人员伤亡和财产损失在规划期内降至预定的目标，确定的在人、车、路、环境和管理等方面应采取的交通安全措施和行动及其实施时序，是各级人民政府及其职能部门科学开展道路交通安全工作、防止道路交通安全工作决策的随意性和盲目性的主要依据和重要手段，是道路交通安全发展的方向与战略，具有保证道路交通安全管理的科学性及避免决策失误的前瞻性作用，对预防道路交通事故具有重要的战略意义。
