针对车载自组织网络中路边单元具有较高碳足迹和部署成本的问题,提出一种车载自组织网络中数据与能量协同的路由算法,通过路边单元间的能量合作及路边单元与下行车辆能量传输的方法,实现网络生命周期最大化.其中路边单元节点可从自然界和车辆中收集能量,并通过能量协作将路边单元节点获得的部分能量传输给邻居路边单元节点.通过分析数据速率、传输功率和能量传输,解决了能量和数据路由中最大网络生命周期的问题,确定了能量和数据路由联合优化策略的必要条件,并基于分布式Lagrange-Newton迭代算法更新数据流、能量流和功率控制,使算法能更快地收敛到最优操作点.实验结果表明,在车载自组织网络中的能量合作框架可有效改善网络生命周期.

To investigate the factors controlling the mineralization in ophiolites we systematically compared the petrology and mineral compositions of the harzburgites/lherzolites, dunites and chromitites in the Luobusa and Purang ophiolites. Generally, the petrological features and trace element compositions of chromite and olivine in peridotite and chromitite are distinctly different between the two *** Luobusa, boninitic melts are inferred to have interacted with the harzburgites and modified the distributions of some trace elements(e.g., Ni, Mn and V) in chromite and olivine. The subsequently formed dunites and chromitites experienced significant elemental exchange. In contrast, the Purang ophiolite contains a wider range of chromitite compositions and records diverse melt activities, such as the growth of relatively abundant secondary clinopyroxene. The metasomatic melts were enriched in Al and depleted in Si, Na and highly incompatible trace elements(e.g., Nb, Zr). Such melts resemble MORBlike melts proposed in the literature but are assumed to be more hydrous than typical MORB because of presence of hydrous minerals. The parental magmas of the Purang dunites and intermediate chromitites are inferred to be compositionally intermediate between boninitic and MORB-like melts. In addition,the more refractory nature of the Luobusa harzburgites facilitated a high Cr concentration gradient with the interacting melts, making it easier to increase Cr in the melts. Crystallization of clinopyroxene and amphibole in the Purang ophiolite accommodated significant amounts of Cr and water, respectively,and negatively affected Cr concentration and chromite crystallization. The concentration of chromite to form chromitites requires the presence of focused melt channels.
