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。

This is the nature of all kingdoms that are self sustaining; we know how to take care of ourselves and survive season after season; for our kingdoms could not have survived so many cycles of nuclear warfare of the human species if we did not know how to sustain ourselves on our own.

这就是所有自我维生的王国的天性：我们知道如何在季节交替中保护自己并一年年幸存下来；因为如果我们不懂得如何自我维生的话，我们也就无法从如此多人类核战争的周期后幸存下来。

Suppose further that sometime in the future, in order to save the human race, scientists set up an enormous self-sustaining machine, just as in the film (minus the scary "Sentinels"), designed to keep the human species alive and reproducing for the 100,000 years it will take for whatever weeds are left on the planet to fix our atmosphere and make the planet once again habitable in a normal way.
