摘要
针对无线网络中的连通支配集(CDS)问题,通过分析得到了CDS的一个重要性质,即简单连通无向图的最小CDS是该图的一棵包含最多叶子节点的生成树中的非叶子节点的集合。根据这个结论,设计了一个新的连通支配集求解算法,实验表明,新算法较前人的算法有更好的性能。
Through in-depth analysis, an important property of Connected Dominating Set (CDS) in wireless network was obtained, in which the smallest CDS of a simple connected graph is the non-leaf nodes of a spanning tree with most leaf nodes. A new CDS algorithm was designed on the basis of the analysis. Simulation results show that the algorithm possess better performance than others.
