担任

I have been involved in motor sport continuously since 1966 firstly as a rally co-driver, as a team principal, and then as a CEO across all the major disciplines of the sport, rallying, rally raid, sports cars, and Formula One working for major manufacturers such as BMW, Ferrari, FIAT , Ford, Maserati, Matra, Mercedes, Nissan, Peugeot Citroen, Renault, and Toyota.

自1996年起，我开始从事赛车运动，从未间断，曾先后担任过公路车赛领航与维修员、团队负责人及各类重要赛车运动的CEO，这些运动包括拉力赛、赛车和一级方程式赛，曾为多个重要厂商服务，其中包括宝马、法拉利、菲亚特、福特、玛莎拉蒂、马特拉、奔驰、尼桑、标致雪铁龙、雷诺和丰田。

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。
