The paper firstly introduces the background, the present situation and meaning of the research on the embedded system. The research of key technologies of embedded ethernet remote measure and control system is carried out in this paper. Then the author detailedly illustrates the design process of hardware and software of the embedded remote measure and control system. The design process includes the selection and configuration of the 32-bit microprocessor, the selection of the memorizer, the selection and software design of the Ethernet Controller, the realization of AD data acquisition model and DA converter model.

The minimality of the virtual backbone is assured by designing optimization algorithm. As a result, it can effectively decrease the overhead of control packets dissemination. Simulation resluts show the correctness and the ability of self- renew.Considering the characteristic of fast-moving in wireless ad hoc networks, we construct a virtual backbone with a independent dominating set. This method can avoid sustaining connectivity between backbone nodes and the bakebone network can be rapidly reconstructed as topology change.

对规模较大、移动较频繁的ad hoc网络，用独立支配集构建虚拟骨干网，克服了骨干节点之间必须维护连通性的问题，使得拓扑变化较快时骨干网的重构能快速实现；采用动态按需路由机制，解决了骨干节点要维护路由表的问题；还利用极大独立集的求解得到极小独立支配集；并通过仿真测试了算法的正确性及自恢复能力。

The good news is that we may have found a potential risk factor for AD that is modifiable.

一个好消息是，我们将有可能发现AD的一个重要的危险因素，而这个因素是可以改变的。
