摘 要: | 在无线传感器网络(wireless sensor network,WSN)中,为更好地构造虚拟骨干网作为路由协议以减少广播风暴,针对不同传输半径,对通过连通控制集构造的虚拟骨干网进行研究,并提出双向圆盘图中的最小连通k-全控制集(minimum connected k-tuple totally dominating set, k-MTCDS)问题,给出了一个集中式近似算法来构造k-MTCDS,通过理论分析,该算法具有较好的近似比。 |
关 键 词: | 组合最优化;最小连通k-全控制集;极大独立集;双向圆盘图;无线传感器网络 |

Abstract: | To alleviate the broadcasting storm in wireless sensor network (WSN), fault tolerant connected dominating set (CDS) whose nodes have different transmission ranges was studied as the virtual backbone in this paper. A general fault tolerant CDS problem, called k-MTCDS (minimum connected k-tuple totally dominating set), was proposed in bidirectional disk graph and a centralized approximation algorithm which has a better approximation ratio was given. |
Key words: | combinatorial optimization; minimum connected k-tuple totally dominating set; maximum independent set; bidirectional disk graph; wireless senor network |
