网格上的分布控制集

Distributed Dominating Sets on Grids

Elaheh Fata, Stephen L. Smith, Shreyas Sundaram

摘要:

本文提出了一种求解网格上近优控制集的分布式算法。该算法的基础是一个现有的集中式算法,构造控制集的网格。对于$m\times n$网格,该集中式算法提供的支配集的大小由$\lceil\frac{(m+2)(n+2)}{5}\rceil$上界,并且其与网格的最优控制数的差上界为5。将集中式和分布式算法推广到$k$ -距离支配集问题,其中所有网格顶点都在支配集中顶点的距离$k$内.

英文摘要:

This paper presents a distributed algorithm for finding near optimal dominating sets on grids. The basis for this algorithm is an existing centralized algorithm that constructs dominating sets on grids. The size of the dominating set provided by this centralized algorithm is upper-bounded by $\lceil\frac{(m+2)(n+2)}{5}\rceil$ for $m\times n$ grids and its difference from the optimal domination number of the grid is upper-bounded by five. Both the centralized and distributed algorithms are generalized for the $k$-distance dominating set problem, where all grid vertices are within distance $k$ of the vertices in the dominating set.
